Justin Chen
I am currently a postdoc at
Georgia Tech, under
Anton Leykin.
My primary research interest is commutative algebra; secondary interests
include (numerical) algebraic geometry and combinatorics.
During fall 2018 I will be taking part in the
Nonlinear algebra program
at ICERM.
I was a mathematics graduate student at the
University of California, Berkeley
from 2012 - 2018. My advisor was
David Eisenbud.
I received a B.S. in Math from Purdue University, where I first learned commutative
algebra from Bernd Ulrich.
You can reach me at "jchen" AT "math.berkeley.edu". My CV can be found
here.
