I am a sixth year PhD candidate at the University of California, Berkeley, planning to graduate and apply for jobs this year.
Read my Research Statement and CV.
I am advised by Martin Olsson. My interests are curves, moduli spaces, and stacks.
I completed my Bachelor's degree in mathematics at Arizona State University.
