I am a computational biologist and an instructor at Stanford University, specializing in spatial multi-omics. I integrate machine learning with a deep understanding of molecular and cellular biology to build scalable, open-source computational tools and apply them to some of the field's hardest open questions: how to define and engineer cell identity for regenerative medicine, how tumor architecture predicts and drives immunotherapy response, and how spatial organization in the brain shapes psychiatric disease and appetite regulation. I develop ML/AI-powered methods for 2D and 3D spatial-omics and apply them to explore the spatial organization of cell types in healthy aging and disease. Through directly mentoring nine students, designing and teaching three custom courses, and contributing to three global health projects, I am committed to building a diverse, equitable, and inclusive lab that empowers the next generation of researchers.

Selected Awards
My (future) lab is built around a central mission: to make 3D spatial biology accessible, interpretable, and transformative for understanding human health. We develop AI-driven frameworks that not only process massive 3D datasets but also make them intuitive and explainable for biologists and clinicians. Our work focuses on two complementary fronts: building user-friendly computational platforms that lower barriers to adoption, and applying these tools to uncover how tissue architecture changes during key biological processes such as aging, cancer initiation, and immune regulation. By integrating multiple data modalities — from 3D H&E to multiplexed spatial proteomics — we aim to reveal both the structural maps of tissue organization and the molecular rules that drive them. In this way, I will train the next generation of scientists to think in 3D, bridging computation and biology to open entirely new avenues for discovery and therapy.
