I am a Ram and Vijay Shriram Data Science Fellow at Stanford Data Science, where I work with Prof. Russ Poldrack and Prof. Christopher Ré on state-of-the-art AI tools that can help us understand the mind and brain (leveraging methods from high-dimensional time-series analysis, self-supervised learning, and explainable AI).

🧠 I am excited about:

  • Foundation models, such as large language and vision models and their application to science outside of conventional deep learning domains
  • Advancing AI methods for high-dimensional time-series modeling
  • Advancing model interpretability beyond current heatmapping approaches
  • Open science
