Learning is key for any type of intelligence. I love thinking about how human learns, and whether that is transferable to machines. Questions like Why ML requires more data than human? intrigue me.

My research interests are interpreting machine intelligence, and aligning AI to human needs. I’m fortunate to be working with Prof. Sarah Dean, Prof. Thorsten Joachims, and Prof. Jennifer Sun at Cornell. Currently, I study reinforcement learning and human-in-loop dynamical systems. Sample-efficient low-rank representation learning for dynamical and unobserved user states is an example of what I work on.
