I am a fourth year Ph.D. student in Computer Science at Stanford University advised by Stefano Ermon, where I'm affiliated with the SAIL and StatML groups. My research interests lie in probabilistic machine learning methods: in particular, I am interested in developing techniques for better adaptation in generative models, robust representation learning, and various applications.

My research is supported by the NSF GRFP, Stanford Graduate Fellowship, and the Qualcomm Innovation Fellowship. I completed my undergraduate studies in CS-Stats at Columbia, where I worked on problems in computational biology as part of the Pe'er lab.

I previously interned at Google Brain in 2019 as part of the Magenta project. In my free time I'm an avid tennis player, runner, and food enthusiast!
