Bio
I am currently an assistant professor at the computer science department in Stanford university.
My research uses tools from statistics to make machine learning systems more robust and reliable — especially in challenging tasks involving natural language. The goal of my research is to use robustness and worst-case performance as a lens to understand and make progress on several fundamental challenges in machine learning and natural language processing. A few topics of recent interest are,
- Long-tail behavior
- How can we ensure that a machine learning system won't fail catastrophically in the wild under changing conditions?
- Understanding
- A system which understands how to answer questions or generate text should also do so robustly out-of-domain.
- Fairness
- Machine learning systems which rely on unreliable correlations can result in spurious and harmful predictions.
Previously, I was a post-doc at Stanford working for John C. Duchi and Percy Liang on tradeoffs between the average and worst-case performance of machine learning models. Before my post-doc, I was a graduate student at MIT co-advised by Tommi Jaakkola and David Gifford and a undergraduate student at Harvard in statistics and math advised by Edoardo Airoldi.
