I am advised by Prof. Chris Ré and affiliated with Infolab and DAWN groups. I am supported by the Stanford Graduate Fellowship and the National Science Foundation Graduate Research Fellowship.

My research interests revolve around making machine learning easily usable for domain experts who do not have access to the powerful systems and massive datasets required for training complex models. I have recently focused on the bottleneck of gathering high quality training data. My projects inlude automatically correcting generative models, debugging training sets, and learning model structure efficiently using priciples from static analysis (coming soon!).

Previously, I worked on problems related to computational imaging. As an undergraduate at UC Berkeley, I studied phase retrieval via partial coherence illumination and digital holography in Prof. Laura Waller’s Computational Imaging Lab. I also rotated with Prof. Gordon Wetzstein’s Computational Imaging Group and looked at solving 3D deconvolution problems more efficiently.

My CV is here.

Teaching

At UC Berkeley, I was a teaching assistant for the first offering of EE16A: Designing Information Devices and Systems and helped develop course material for the class as well. I was also a teaching assistant for EE20: Structure and Interpretation of Signals and Systems.
