Hello. I am a fifth-year computer science Ph.D. student at the Courant Institute of Mathematical Sciences at New York University. I am a member of the Machine Learning for Language (ML²) group (subset of the CILVR group). I am advised by Profs. He He and Kyunghyun Cho. I also frequently collaborate with Prof. Sam Bowman. Since October 2022, I have been (on-and-off) a Visiting Researcher at Fundamental AI Research (FAIR) at Meta, mentored by Dr. Jason Weston.

My research focuses on natural langauge processing and machine learning. Specifically, my interests include text generation (learning from reward, learning from feedback, machine translation, dialogue, decoding, uncertainty, etc.), reasoning, and scalable oversight. More recently, I have been trying to learn more about multi-modal NLP.

Prior to my Ph.D., I graduated from the University of Chicago (B.S. in mathematics and B.S. in computer science). At Toyota Technological Institute at Chicago (TTIC) and the University of Chicago, I worked on text generation and structured prediction with my advisor Prof. Kevin Gimpel. In Summer 2020, I was a Research Intern at Google Research New York; in Summer 2021, I was a Research Intern at Google Brain. I also hope to advance access to cutting-edge NLP: I co-organized and co-instructed NYU AI School mainly targeting NYC-area undergrads (2022, 2023); I also co-instructed the Deep Learning for NLP course at the African Masters of Machine Intelligence (2022).
