I'm currently a (soon-to-be-graduating) PhD student in computer science at Stanford University, working with Percy Liang and the Stanford NLP group. If you'd ever like to reach out to me, just shoot me an email at

I am interested in studying how natural language processing can be tooled to make it easier for people to understand and consume information. On a related note, I care about how we can bring greater transparency, accountability and fairness in voice through information summarization. I believe that both these goals need us to rethink how we evaluate our models and my more recent work seeks to address this problem using a mix of statistics, crowdsourcing and natural language processing.
In the past, I have worked on providing guarantees for learning latent variable models, probabilistic programming, statistical relational learning and hierarchical reinforcement learning.
