Hi! I’m a fourth-year PhD student in computer science at Stanford University. I conduct research in natural language processing and machine learning. I am grateful to be co-advised by Chris Manning and Percy Liang, and to be supported by an NSF Graduate Research Fellowship.

I conduct basic research, asking:

  • how can we know what unsupervised language learners know?
  • how can we leverage our understanding to build systems that learn language better?

with the aim of enabling the long-term development of systems to improve human communication and education.

Feel free to look me up on Google Scholar or Twitter, or take my CV.

In the summer of 2022, I’m interning at DeepMind in London! Please reach out to me if you’re in the area (broadly construed) and would like to meet or chat.
