Hi! I am a PhD student (since fall 2019) focusing on natural language processing and machine learning at the University of Southern California, where I am advised by Robin Jia. My current interest is in adaptive data collection. Previously, I earned a B.S. in Mathematics at the University of Massachusetts Amherst. When there are slow weeks at school, I can be found lifting myself at the USC Parkside calisthenic park or riding my bikes to places within driving distance. Oh yeah, I also try to read different books.

If you would like to get in touch, feel free to email me! I am currently looking for an internship for the summer of 2022.

I have written a few tutorial pieces and application essays; I hope it may be useful to some people. More articles to come!


  • If you find yourself fixated on unhappy or unpleasant thoughts, you may benefit from therapy. I think resolving emotional difficulties need dedicated time and effort, and therapy is a constructive way to accomplish this. If you are a USC student, we have excellent resources (book an appointment on MySHR or call (213) 740-9355). If you are a student at an university in the US, check in with your health services to see if therapy and counseling services are offered - more may be available than you think!
  • I recommend How to Avoid a Climate Disaster for everyone, especially if you're an undergraduate or younger.
  • I recommend Buddhism Without Beliefs: A Contemporary Guide to Awakening for a patient reader; the book might offer an interesting insight or two. As an alternative, Four Thousand Weeks: Time Management for Mortals can be a better read - lookout for the Buddhist themes throughout the book!
