What is your position or role in the DESI project?
I am a senior postdoc working on the cosmological analysis of DESI data.

Where were you born?
Cáceres, a small city in western Spain.

Where do you live now?
Barcelona, a big city in eastern Spain.

What do you do as part of DESI?
I am very active in the Lyman alpha working group. Among other things, I am leading a cosmological analysis of the one-dimensional power spectrum of the Lyman alpha forest.

What is the most interesting or exciting thing about your job?
I genuinely love doing research in cosmology. It is incredibly exciting to explore fundamental questions about the nature of our Universe every single day!

Any advice for an aspiring scientist?
Being a scientist takes dedication and hard work, but it’s deeply rewarding. If you share a passion for science, pursue it!

What do you do for fun?
I play with my daughter, watch TV series, read books, etc.

If you weren’t a scientist, what would be your dream job?
No idea! 🙂

What excites/interests you most about DESI?
DESI is giving us the most constraining data up to date, allowing us to put the strictest constraints on the nature of dark energy.
