I am a 4th-year Ph.D. student in Computer Science at Stanford University working at the intersection of biomedicine and AI. I am very fortunate to be advised by Aaron Newman and Emma Lundberg. My current research focuses on 1) tissue cellular composition and 2) subcellular protein localization, where I develop machine learning models for multi-omics data, with the goal of improving our understanding of the mechanism of diseases, like cancer, and enabling personalized treatment. Previously I have also worked on graph representation learning, natural language processing and regulatory genomics with Jure Leskovec and Anshul Kundaje.

Before Stanford, I was an AI Resident at Google Research working with Michael Collins on pretraining multimodal vision+language models. I was also a research intern at Google Research in summer 2019 working with Dan Roth and Ian Tenney on probing pretrained language models.

I received my B.S. in computer science at UIUC in 2019. I did research with Jiawei Han on data mining and heterogenous graph representation learning.
