Research
I am a second-year Ph.D. student in the CS theory group at the University of Colorado Boulder advised by Dr. Joshua Grochow. I am interested in applications of algebra to complexity theory. This includes algebraic models of computation, geometric complexity theory, arithmetic circuits, tensors and matrix multiplication, algebraic combinatorics, polynomial computation, and algebraic proof systems.
Currently, I am thinking about the tensor isomorphism problem under the lens of representation theory and algebraic geometry.

About Me
I am originally from San Francisco. I have been to 29 US states and 11 countries outside the US.
My Erdős number is 3. Paul Erdős → László Babai → Joshua Grochow → me.
My main hobby is fencing, which I began in late 2015. Feel free to ask me about it, at the risk of a very long conversation.
