What is your role in the DESI project?
I’m involved in the Milky Way Survey, where I contribute to the target selection and the definition of the Backup program, currently lead the MWS Visual Inspection efforts, and help out as a DESI observer. One of my roles was to work on the target selection of white dwarfs, which DESI is observing as secondary flux standards (white dwarfs are usually very blue, and have relatively simple and well understood spectra. Well, most of them).  Within DESI, I’m probably the person with the lowest redshift: my science interests are stars in the solar neighborhood, in particular within 100pc.

Where were you born? Where do you live now? What are the interesting places that standout that your work has taken you to?
I was born and grew up in Berlin. One of the first questions I get asked is “which part”: West Berlin. During the cold war, it was pretty much the same as living on an island. Now I’m settled in the Midlands in the UK, which are very beautiful. That is, once the Sun comes out. I love being at observatories. All of them. Each and every one of them is very different: The views over the Arizona desert from Kitt Peak are just stunning (and their food is very nice).  Paranal is the true definition of desert, and the platform with four VLTs, one of them firing a quad AO laser, seems straight out of a science fiction movie. La Palma has some of the most varied landscapes (words can’t capture what it feels being on the rim of the Caldera). And being chased by wild boars in a moonless night at Calar Alto stands out as a memory.

What would you say is the most interesting or exciting thing about your job?
Three very different aspects come to my mind. I really enjoy working together with so many amazing people from all over the world and of all ages, that have such an enormous range of skills and knowledge. Thanks to them, I learn something new every day.  Then there is the huge satisfaction of answering a scientific question, pushing the boundary of our knowledge just that one step further. And finally, the day-to-day work is just great fun. I’m a data junkie, and with the rapidly growing number of ground and space-based photometric and spectroscopic surveys, there is no end to discovering new exciting things out there in the Universe.

Any advice for aspiring scientists?
Find out what you are good at, sharpen those skills, and then make good and constant use of them. Just like you would do when learning to play an instrument, or practice some sport. Keep questioning the things you think you know. Read a lot of papers and listen to a lot of talks spanning a wide range of topics. Look out for that odd small inconsistency in your data (or equations), turn it into a question, and then try to find an answer.

Finally, what do you do for fun?
Hey, astronomy is a lot of fun. But so is cycling, climbing, cooking, traveling, and spending time with friends and family.

What is your role in the DESI project?
I am the co-chair of the Cosmological Simulations Working Group, which means I help organize the efforts to produce simulations of the maps of galaxies that DESI will make.  These simulations help us figure out the ingredients that went into the early universe, even though we can only look at the final product—the galaxies today.  It’s kind of like trying to figure out the ingredients of a cake by tasting it: you can make a good guess based on the flavors, but if you really want to know if you got the recipe right, you have to try to bake it yourself and see if it comes out the same.  That’s what we do, thousands of times over, with our simulations.

Day-to-day, I write and run simulations and tools to help the DESI collaboration use the data.  I write papers about the simulation techniques and tests we come up with to show that our simulations are high enough quality to match the amazing data being delivered by the DESI observations.

Where were you born? Where do you live now? What are the interesting places that standout that your work has taken you to?
I was born in Virginia, USA, grew up in the Philadelphia suburbs, and currently live in NYC.  I was always interested in astronomy, but I sort of stumbled into studying it in undergrad after taking an introductory course.  When I got to the cosmology courses, I was hooked!

Astronomy has given me many amazing travel opportunities, starting with Tokyo for an undergrad summer research project.  Since then, I’ve been to conferences in Munich and Lisbon, and a summer school in Chile—that’s the Chilean summer, so I got to dodge the North American winter!  I’ve gotten to visit observatories in the German Alps and the Chilean desert—the latter was really special, because it’s one of the darkest observing sites in the world, and you can see the Magellanic Clouds since it’s in the southern hemisphere.  The Magellanic Clouds are a pair of satellite galaxies that orbit our galaxy; I had written my undergrad thesis on them, but had never seen them myself until that trip to Chile.

What would you say is the most interesting or exciting thing about your job?
I work on cosmological simulations, which are computationally demanding and require supercomputers to run.  I love the challenge of squeezing every last ounce of performance out of a supercomputer, especially when doing so helps us learn something about the universe.

Any advice for aspiring scientists?
Astronomy is full of opportunities to combine your interests. Interested in astronomy and earth science?  You can study exoplanet atmospheres. Astronomy and machine learning?  There’s gravitational lens identification in telescope images.  Astronomy and high-performance computing? Cosmological simulations (that’s me!). These are just a tiny fraction of the interdisciplinary possibilities!

And don’t be afraid to challenge yourself—as an undergrad, I knew computer science came more naturally to me than astrophysics.  But studying astrophysics has proven rewarding exactly because it was challenging.  Doing something challenging is often where we have the biggest opportunity for learning and growth.

Finally, what do you do for fun?
In pre-COVID times, I did tango dancing and rock climbing.  These days, I like to explore the many parks of NYC on foot, and when the weather keeps me inside, I like to play video games and dream up the latest plot twist for my Dungeons & Dragons campaign.

What is your role in the DESI project?
I am the lead on a key science goal of DESI, the selection of the biggest Bright Galaxy Sample (BGS) to date which aims to measure the positions to 20 000 000 galaxies over 14 000 square degrees with a median redshift of z ∼ 0.2. I’m also in charge of providing the Survey Validation BGS targets. I’m an active member of the BGS and target selection working groups.

My main work involves the construction of the BGS target catalogue for DESI and for this I use the Legacy Surveys Imaging data. Efficient target selection is central to achieving the scientific goals of BGS. I implemented a new way to do star-galaxy classification exploiting a combination of GAIA’s compact point spread function (PSF) and model magnitudes from the Legacy Surveys (LS) pipeline TRACTOR. My work also involves the assessment of the target catalogue using other datasets such as SDSS and GAMA galaxies, as well as mock galaxy data like the MXXL light-cone catalogue. My work also focuses on galaxy clustering analysis and mitigation of systematics.

Where were you born? Where do you live now? 
I was born and raised in Colima, Mexico, a beautiful Mexican state with two volcanoes and nice beaches. Since 2017, I live in the beautiful city of Durham, UK. Famous for its almost 1000 years old Cathedral, and for being the filming place of some of the Harry Potter movies.

What would you say is the most interesting or exciting thing about DESI?
I guess the most exciting thing is the opportunity to unveil the mysteries of our Universe with one of the most ambitious surveys of the time as DESI is. But, beyond that astonishing thing, is the fact that there’s no recipe for many things, and so you have the opportunity to be the first in creating this new knowledge. For instance, building the BGS target catalogue, I have to come up with new ways to identify spurious objects or fake galaxies. For this effort, besides the data analysis I normally do, I found some motivation to dip into web development and create an interactive webpage to carry visual inspection of the Legacy Surveys Imaging.

Any advice for aspiring scientists?
Quoting Coldplay, “nobody says it was easy…” but hey, you definitely will enjoy the road, especially when you do what you like. Don’t be afraid to be wrong or to not know things, as Richard Feynman used to say “I have approximate answers and possible beliefs, different degrees of certainty about different things but I am not absolutely sure of anything, and in many things, I do not know anything about it …”

Finally, what do you do for fun?
I occasionally do outdoor games and sports. I like to play table tennis and someday I would like to practice some real tennis. I like coding for fun and to learn new programming tools. I am a bit of a foodie person, so I like to try new dishes and also like to cook occasionally. But the thing I do enjoy the most is playing with my son.

Anything else you’d like to share ?
Yes. Thank you, DESI! Thanks to this collaboration I’ve learned plenty of things and meet wonderful people on the road. The experience I’ve gained with DESI opens many doors in my career, and that’s something I will always be grateful for.

What is your role in the DESI project?
I work on the large-scale clustering patterns of galaxies and quasars, and how we can learn about cosmology from these measurements, in particular how dark energy has been changing the expansion history of the Universe. I’m especially interested in developing new types of these analyses based on ”voids” in the galaxy distribution. But right now I’m also learning about the details of observing galaxy spectra while contributing to the visual inspection effort of early data, and preparing for my first remote observing run later in the year.

Where were you born? Where do you live now? 
I was born in Delhi, India. I live in Portsmouth, in the UK. Work took me to the wonderful far north of Europe, in Helsinki, where I worked as a postdoc for two years and where the sea would freeze over in the winter—but the most interesting place has to be a safari game reserve in KwaZulu-Natal, South Africa, which was the venue for a week-long cosmology conference I once attended!

What would you say is the most interesting or exciting thing about DESI?
The most exciting feeling as an astronomer is that brief eureka moment when you solve some interesting problem, and for a short time you get to feel that you are the only person in the world who knows the answer to a question that lots of people might be interested in… but these are pretty rare! More commonly, the best thing about it is the opportunity to interact with really clever, motivated and interesting students and colleagues every day.

Any advice for aspiring scientists?
Science is tough, but it is extremely rewarding so it’s worth sticking at it. Try to work with and learn from as many people as you can—it’s a collaborative effort!

Finally, what do you do for fun?
I like to say I’m a rock climber and mountaineer. The truth is that I haven’t been able to do any serious climbing for a long time, because work and kids and other things have taken up my time, but it’s still an important part of my identity! Nowadays (at least, pre-Covid) I enjoy playing squash instead.

What do you do as part of DESI (both generally and day-to-day activities)?
I mostly work within the Lyman alpha working group (the science team in DESI that focuses on extracting information from quasar spectra in order to learn more about the history of the universe). Alongside with Michael Walther I am co-lead of the Picca task force (Picca is the analysis code developed to process quasar spectra). We work on the development of the analysis pipeline Picca, and we coordinate the team of developers. On a day-to-day basis I participate in many working group discussions where we discuss the research of the different members. I identify potential defects on the analysis and coordinate the actions required in Picca to fix/test them.

Where were you born ? Where do you live now ? What are the interesting places that standout that your work has taken you to?
I was born in a very small town near Barcelona, and I now live in Paris. I’ve also been living in Marseille and the Canary Islands! My work has taken me to several places both in Europe and the US.

What would you say is the most interesting or exciting thing about your job?
For me, the most interesting bits of scientific research are the sense of accomplishment once you finally solve the puzzle you are into, and the sense of seeing things no one else in the world has seen yet.

Any advice for aspiring scientists?
Create a plan: what do you want to do in the next 5 years? And in 10 years? Where do you want to live? Yes, I think it is more important to live in a place you like rather than having a “better” position. Detail the initial stages of the plan, and just have a broad idea of what you want to achieve. Focus on the opportunities and modify the plan as necessary. And always have a backup!

Finally, what do you do for fun?
I like to do many, many things: climbing, biking, hiking (mostly in the mountains), dancing, cooking. I also enjoy a lot “Castells”: we create human pyramids that go up six stories or even higher!

What do you do as part of DESI?
I have developed the auto-guiding system, an algorithm that analyzes the stars in the field and provides corrections to the telescope, driving it to the exact target location and stabilizing the telescope motors in that precise sky position during the entire exposure. This system is key to ensure the light from the target galaxies fall into each of the 5000 fibers. Any mispositioning or tracking error would prevent the light entering into those tiny fiber holes, decreasing the spectra signal-to-noise, reducing the survey efficiency and causing contamination from other sources. I have been part of the commissioning of all three of the following instruments: ProtoDESI, Commissioning Instrument and finally DESI. After many nights of tests at the Mayall telescope, we managed to reach the tight requirements on guiding accuracy and tracking.

Where were you born? Where do you live now? What are the interesting places that standout that your work has taken you to?
I was born in Barcelona and continue to live and work here. Thanks to projects like DESI, I had the opportunity to visit the most outstanding observatories on earth, such as El Roque de los Muchachos in the Canary Islands, the Cerro Tololo Interamerican Observatory in Chile and of course, DESI’s home, Kitt Peak National Observatory in the US. Astronomers and people working in observatories have something special and always lead to interesting conversations during the long nights of observation.

What would you say is the most interesting or exciting thing about your job?
The fact that with our algorithm we can move the Mayall telescope weighting 375 tons with a precision of a few milliarcseconds is really awesome!

Any advice for aspiring scientists?
Bring your own and risky ideas. Common and logical things have already been done and we won’t discover anything new with the things we know.

Finally, what do you do for fun?
When I had less kids at home I used to make films and build drones. Now I am playing with them and looking forward to build more things together once they grow.

What is your role in the DESI project?
I am a second-year PhD student and I help test the algorithm which assigns our 5,000 robotically-controlled fibers to targets. I also search for intrinsic alignment in DESI galaxies and am part of the outreach team! Most of my time is spent figuring out the best way to condense a lot of different information into a format that’s easy to communicate—whether it be summarizing the results of fiber assignment, finding a good statistic to quantify galaxy alignment, or explaining a cosmology idea to the public.

Where were you born? Where do you live now? What are the interesting places that stand out that your work has taken you to?
I was born in Kenya but spent most of my life in Colorado. Now I live in Massachusetts, where I’m attending school. A few years ago I got to spend a summer on the big island of Hawaii and observe on one of the largest telescopes in the world! That was a very memorable adventure, and since then I’ve been able to go back twice thanks to astronomy.

What would you say is the most interesting or exciting thing about your job?
I’ve only been working on cosmology for a year, so for me the most exciting part about my job is that I’m learning something new every day. I get to explore the details of fascinating questions: How did the universe begin? How is it structured? What’s the deal with dark energy? And get paid for it! Being part of DESI, I also really enjoy getting to collaborate and make friends with astronomers all over the world.

Any advice for aspiring scientists?
You don’t have to be a genius to be a good scientist. I’ve loved astronomy since kindergarten, but up until my first year of college I was certain that I wasn’t actually smart enough to be an astrophysicist. I eventually realized that persistence and creativity can go a long way, and I was smarter than I was giving myself credit for! The most admired scientists around me are not ones who immediately know the answer to every question, but those who have creative ideas and think about problems differently than others. Also learn to code.

Finally, what do you do for fun?
Play music! I collect different types of instruments and love learning new ones. My favorite right now is the pipe organ. I also like to bake—especially astronomy cakes.

Below is one of Claire’s marvelous creations in the shape of the Mayall telescope.
More of her creations here! 

What is your role in the DESI project?
I’m a member of the DESI scientific research staff at NSF’s NOIRLab, where our team works to ensure that DESI performs as expected and will continue to do so throughout its many upcoming years of operations. I’ve been heavily involved in the DESI target selection imaging surveys for over five years. As part of this effort, I’m responsible for processing roughly a quarter petabyte of NASA infrared satellite images. Recently, I’ve shifted toward working with the DESI commissioning team that’s testing all of the newly installed DESI hardware at Kitt Peak’s Mayall telescope via a campaign of preliminary sky observations. Within the DESI commissioning team, I’ve created image processing pipelines to analyze data from the commissioning camera and guider cameras.

Where were you born? Where do you live now? What are the interesting places that standout that your work has taken you to?
I grew up in Bellevue, Washington. I currently live in Tucson, Arizona. The past travel opportunities that stand out to me are DESI-related trips to England and Spain for collaboration meetings, and visiting Cerro Tololo Inter-American Observatory in Chile. Kitt Peak is also great–even though it’s only about an hour’s drive from Tucson, it’s still a world-class astronomical site.

What would you say is the most interesting or exciting thing about your job?
In terms of DESI, I really enjoy working with my fellow collaboration members, who are all extremely talented in different areas of technical expertise. I like that I’m continually learning a lot from interacting with DESI collaborators across many institutions and specializations. More generally, as a scientist, my favorite research projects are those that involve mining huge data sets for rare discoveries.

Any advice for aspiring scientists?
Nowadays there are many ways for everyone to get involved with scientific research, particularly through crowdsourced science initiatives in astronomy and other fields. The Backyard Worlds: Planet 9 project that I co-founded is one such example. Getting involved in crowdsourced science can be a great way to see what the research process is really like in practice, and to learn new skills that will have value even outside of careers in science.

Check out Backyard Worlds Planet 9 project! https://www.zooniverse.org/projects/marckuchner/backyard-worlds-planet-9 

What is your role in the DESI project?
I co-chair the DESI time domain working group. The goal of our team is to study the transient Universe: we want to find and characterize explosive events such as Supernovae and kilonovae, the disruption of stars close to supermassive black holes in the center of galaxies, and even the variability of binary stars within our own Galaxy. We are interested in studying the physics behind the processes that happen within this transients, such as the accretion of mass in binaries and the creation of the heaviest elements of the Universe, but we also want to use some of these events to understand the dynamics of the Universe. In other words, we will also study cosmology with these events.

What have you been working on recently?
Currently, I am organizing the time domain working group activities. Within the working group, I have been leading efforts on potential science analyses that involve DESI and gravitational wave detections. In particular, I have been looking into using the DESI galaxies to do cosmology with gravitational waves from compact object binaries, such as binaries containing neutron stars and black holes. I am also studying how we can use some of the DESI fibers (some of the DESI 5000 “eyes to the sky”), to look at interesting emission from these binaries, and more in general, from transients that are detected in the sky by other experiments. In other words, I am interested in following up interesting objects and use them to understand the expansion and content of the Universe.

Where were you born, where do you live now?
I was born in Rome, Italy. I grew up and studied there, until I moved to London for my PhD at UCL. Now I live the Chicago suburbs, I am a postdoc at the Fermi National Accelerator Laboratory and an associate fellow at the University of Chicago. I like to say that Chicago is the Rome of the US, so I feel at home here!

What would you say is the most interesting or exciting thing about your job?
What I love about my job is the possibility of constantly coming up with new ideas and perspectives to understand the Universe through different angles. I find that there too many interesting things I would like to work on, so I often don’t have the time to pursue them! I also love the possibilities that a big collaboration such as DESI gives to its members: the science possibilities are so broad that all of us get to learn about many different topic, and interacting with collaborators from a different field always brings to exciting new analyses, ideas and results.

Any advice for an aspiring scientist?
Society might teach us that there are fields other than science that are more important and that will make you more successful in life. Do not believe that, and if science is your passion, then never give up on your dream! Science is at the base of our everyday life even when we do not realize it, and astronomy in particular has always been one of the most inspiring science fields since the most ancient days of humanity.

What do you do for fun?
When I am not working, I love to do sports. I practice every day: I play beach volleyball competitively, and when I am not doing that, I love to do CrossFit. Olympic weightlifting is one of my favorite things in Crossfit! I also love to listen to music, go to concerts (rock, jazz, blues, electro-swing,…), and to the theatre.

What is your role in the DESI project?
I manage the work at the Mayall Telescope in support of the DESI project. During the installation phase, this consisted of daily oversight and planning updates for the installation work plan. Now that installation is complete, I coordinate the daytime work of the engineering and technical staff with the nighttime science observing. In doing this, I work closely with Klaus Honscheid, Paul Martini, Connie Rockosi, and many others.

Where were you born? Where do you live now?
I was born in Chattanooga, Tennessee, USA. Before coming to NOIRLab, I’ve lived in three different countries across ten different time zones. I live now in Tucson, Arizona, USA. In normal times, I spend roughly half my time in the NOIRLab offices and the other half at the telescope on Kitt Peak.

What would you say is the most interesting or exciting thing about your job?
The most interesting thing is the constant flood of opportunities to learn new things. I’ve absorbed so much about new technologies for instruments from the DESI project, that I sometimes forget all the fascinating cosmology that I’ve learned as well. The most exciting thing is the chance to contribute to a science product that will have enormous lasting value to the cosmology and astrophysics communities. And the most fun thing is working with so many people from so many different backgrounds who know so much more than I do about what they’re doing. DESI project people are always fascinating to talk to!

Any advice for aspiring scientists?
1) Stay curious; always wonder “what?” and “how?” and “why?”
2) Don’t ever be afraid to talk to people you don’t know. That’s how you learn.
3) Don’t get discouraged. Most things or ideas don’t work the first time. Keep trying anyway.

Finally, what do you do for fun ?
I enjoy bicycling, hiking, going for walks, dining out, and being with my family especially outdoors.

What is your role in the DESI project?
I have been working on the imaging surveys for the last 5 years or so. DESI is a survey to build a 3D map of the universe. We need to know ahead of time where to point DESI’s optical fibers to collect light from the distant galaxies that we want to map. We do this by taking regular images of the sky, building 2D maps, and measuring all the stars and galaxies in these maps. We select promising galaxy targets for follow-up with DESI based on their shapes and colors in 2D. DESI allows us to measure the all-important third dimension—redshift or distance—for these galaxies.

The cosmology goals for DESI require that we have a very uniform and well-understood set of target galaxies that we start from, and this means having sensitive images and careful measurements of the stars and galaxies they contain. No existing imaging surveys were sensitive enough, so we had to do our own! We used three different telescopes and cameras, in Chile and in Arizona, to collect all the images we need. We also use infrared images from the WISE space telescope operated by NASA.

What do you do as part of DESI?
In the early stages of this work, I was part of the team that went to the telescopes to carry out observations. All together, we spent over 1000 nights to collect these images. I love traveling to the telescopes; the secluded mountaintops are very quiet and peaceful, and the high desert terrain is starkly beautiful. Even though it’s very tiring working long night shifts, we get into the rhythm of the sky, watching sunset and sunrise, moonset and moonrise, and even the rise and set of the Milky Way galaxy.

All our imaging observations are finished now, and now we are focusing on the computer programs that detect and measure the stars and galaxies in the images. This is tricky because we have images taken in a variety of conditions—lots of clear and still skies, but some turbulent skies, and even light clouds on occasion. We need to squeeze information from all these images, so we have to take into account what the atmosphere has done to the appearance of the galaxies in each image. We’re currently working on our ninth full processing of our full image collection—Data Release 9 from the DESI Legacy imaging surveys.

In practice, I spend most of my day writing and debugging computer programs, figuring out where and why the software fails and how we can improve our processing to make the best measurements we can.

Where were you born? Where do you live now?
I was born in Squamish, near Vancouver in western Canada, and grew up in the Kootenay region, in the mountains. I did my PhD in Toronto, followed by postdoctoral work in the USA for five years, then moved back to my partner’s hometown of Waterloo, Ontario.

What would you say is the most interesting or exciting thing about your job?
I just think it’s amazing that we can measure things about galaxies that are billions of light-years away, and figure out the shape and evolution of the whole universe. Day to day, I spend a lot of time writing computer code and looking at images of galaxies, and galaxies just look amazing! Most of the galaxies we will observe with DESI are so distant that they just look like tiny smudges, but nearby galaxies are just endlessly amazing.

I also have the privilege of working with a bunch of very smart, interesting, and dedicated people every day. It takes hundreds of highly skilled and specialized people, with overlapping knowledge and interests, to make a complicated project like DESI work. I’m an expert in a tiny little corner of the project, and it’s amazing to me that we can all coordinate our little patches of expertise to build something truly amazing.

Any advice for aspiring scientists?
One of my advisors says “don’t choose what you work ON, choose who you work WITH”. That might be a little extreme, but modern observational astronomy is a large collaborative undertaking, and working with people you like and respect is one of the things that makes it really fun. Big science projects require all kinds of people, so don’t worry that you don’t know everything (nobody does!). Follow up things that seem interesting to you! Keep in mind that a lot of the science stories you see in the news are the results of years or decades of work—some days are thrilling, and some days are just a grind like any other job; persistence is really important.

Finally, what do you do for fun?
I have a family (partner plus kids ages 9 and 11) and we like to go camping and hiking and dig in our garden.

What is your role in the DESI project?
I am a member of the DESI Lyman-alpha working group. In addition to this, I help organize the biweekly DESI Research Forum.

What do you do as part of DESI?
My work involves building better mathematical models of the Lyman-alpha forest power spectrum and its cross-power spectrum with other cosmological tracers such as quasars. On a day-to-day basis over the last several months, I have typically either been working on analytical perturbation theory calculations, numerically computing them, or playing around with simulation outputs. Our goal is to test these improved models against simulations and data in hopes of better understanding the high-redshift universe and more accurately determining cosmological parameters.

Over the last couple weeks, a panel of DESI members began organizing a new biweekly research forum. I am a member of this panel and spent time helping in this effort. Going forward I plan to be involved with recruiting speakers and organizing talks.

Where were you born? Where do you live now?
I was born in Miami Gardens, Florida, and I currently live in Columbus, Ohio.

What would you say is the most interesting or exciting thing about  your job?
The opportunity to better understand our universe is the most exciting thing about my job. Sometimes I have to take a moment and step back from the difficulties of day-to-day life to remind myself that, in some sense, I get to study the very thing in which all else exists. Nothing else I’m familiar with interests me more!

Any advice for aspiring scientists?
At times you may feel discouraged from pursuing science because the work gets difficult and you begin to doubt your ability to be successful. Remember that every discovery made or new idea developed came from some person doing what they enjoy. None of those people were magical or possessed superhuman abilities. If they can find success then so can you.

Finally, what do you do for fun?
I enjoy trying my hand at cooking different dishes and going out to sample the local cuisine. When the weather permits, I try to spend time outdoors at the park and checking out various events in Columbus.

What is your position or role in the DESI project (both generally, and day-to-day activities)?
I am the point person for tiling and fiber assignment needs during the Commissioning Instrument and the various science programs embedded in late Commissioning phase. I will also do this for the Survey Validation phase of DESI. This work has led to some software development and creation and maintenance of some visualization tools. The nature of the commissioning of an instrument demands a daily regroup and change of plans based on the ongoing discussions/analysis; the spectrographs and fiber positioner tests require a wide variety of tile designs and quick turnaround in their content and format. Catering to the needs of these tests has been part of my daily routine over the past five months. There was an extended 9 months-long period of preparation prior to the first light which took the largest chunk my days.

What would you say is the most interesting or exciting thing about DESI (and/or your job and/or astronomy in general)?
The comprehended scales of time and space by us neurologically advanced yet biologically limited creatures, is remarkable.
More astonishing is the notion that this breadth and depth of knowledge is only attained by capturing tiny pockets of energy from the sky and really not much else. To ponder clever/creative ways to derive information from 3% of any complex system to have a clue about the remaining 97%, even if never fully understood/resolved, is one of the most honorable parts of the human heritage.
DESI is making the largest 3D map of the universe and helping to probe such a vast volume of the physical universe we inhabit, in however minuscule way, is a worthwhile endeavor.

If you were not a scientist, what would your dream job be?
Strangely, at this moment, nothing comes to mind as a dream job I would want to have. It could be a temporary state of mind or it could be because I attempt to do a bit of all I want to do as part-time jobs here and there while I keep an interesting day job; but maybe time investments would be different in other life realizations. Perhaps I would be an artist who does science in spare time as opposed to a scientist who creates art in spare time.

Any advice for aspiring scientist?
Do not hesitate to ask your questions. You’d be surprised by the number of people who do or will have the same question; so your challenge becomes their quest as well; and what’s better than partaking in a collective search for knowledge.

What do you do for fun?
This [i.e., pleasant/meaningful interactions of similar nature]. Paint. Fly. Hike.

What is your role in the DESI project?
In the past, I’ve largely taken highly polished versions of data and attempted to draw definite conclusions about our Universe, in particular whether we understand gravity as well as we think we do.

For DESI, I’ve gotten closer to the dark art of creating this data and tried to better understand how this might affect the conclusions we can draw. On a day-to-day basis, I mostly plug gaps by trying to solve the latest problems, which is great. I enjoy the freedom and learn a lot, but anticipate a more coherent role in the future.

Where were you born? Where do you live now?
Glengormley, Northern Ireland. Slightly different from my current abode of Berkeley, CA!

What would you say is the most interesting or exciting thing about DESI?
I’ve never been this close to a telescope before so everything is new. The people are great and my primary motivation is what we will learn about the birth of the Universe. It’s fantastic that we can say anything at all. I confess that I also spend a lot of time thinking about what we might do better next time around.

If you were not a scientist, what would your dream job be?
Likely something soccer related.

Any advice for aspiring scientists?
Get involved early and ask around. There’s often a snowball effect and you won’t know where you will end up.

Finally, what do you do for fun?
Surfing, sailing, cycling and soccer. Not necessarily in that order. I’m also a budding wood working enthusiast.
