Hi! I am a first-year PhD student in computer science at the University of Washington, advised by Yejin Choi and Noah Smith. I graduated this Spring from Northwestern University with majors in computer science and math. There, I was super fortunate to work in the fields of natural language processing and computer audition with Professor Doug Downey, Professor Bryan Pardo, and Dr. Prem Seetharaman.

Some study guides I've made

I really enjoy making study guides! Here are a couple I'm especially proud of, and I hope they are useful resources for other students. …
