About

I'm a second-year PhD student at Brown University advised by (the incredible) Ellie Pavlick. I also work with Stefanie Tellex and George Konidaris and a lot of the other wonderful people at Brown.

As an undergrad, I was advised by Ani Nenkova and Byron Wallace in various areas of language processing and machine learning. My research uses language to structure reinforcement learning, aiming towards building more intelligent, interpretable and ethical agents. Specifically, I'm interested in building models for natural language understanding using a combination of compositional, logical methods and deep representations to help uncover better "meaning representations" that can help across a variety of grounded tasks. I'm also interested in modeling and introducing concrete world knowledge representations into existing models; specifically in settings that require agents to co-ordinate and reason pragmatically in different cooperative contexts.

Apart from work, I enjoy reading vast amounts of literature, various kinds of music and mostly just programming for fun. Feel free to reach out with research related questions or otherwise!

Research

What I’m most interested in is building systems that can infer knowledge, reason and act in the way that humans do, by creating frameworks that incorporate language knowledge, RL exploration strategies and human-level inference. This includes modeling interactions between agents that first reason and respond with respect to goal-oriented information at hand, but then also allow world knowledge to alter their reasoning. More recently, I’m interested in learning semantic correspondences between language, images and mental depictions of concepts we encounter and learning semantic representations for structures in text.
