Francesc Castella

I am a Hedrick Assistant Adjunct Professor in the Department of Mathematics at UCLA.
Starting in September 2016 I will be an Associate Research Scholar (non tenure-track) at Princeton University.

Office: Math Science 6939

My CV as of July 2016.

Research Interests: p-adic L-functions, Euler systems, and their variation in p-adic families,
with a special emphasis on their applications to the arithmetic of elliptic curves and modular forms.
