About Me
Lia Lammert
I'm 24 years old, and half-french, half-korean.
I have just started a PhD in cosmology at the APC laboratory (Astroparticles and Cosmology) in Paris. I will be working on a data analysis pipeline for galaxies as part of the LSST project.
I really enjoy learning new things — "La joie d'apprendre"!
