Ryo Kamoi

I am an incoming CS Ph.D. student at Penn State University advised by Dr. Rui Zhang. I received my master’s degree in CS from UT Austin where I was advised by Dr. Greg Durrett, and received my bachelor’s degree in Statistics from Keio University where I was advised by Dr. Kei Kobayashi.

I’m interested in building reliable and explainable NLP systems.
