I am a Ph. D. Student in the Department of Statistics at the University of British Columbia, supervised by Ben Bloem-Reddy. I’m broadly interested in causal machine learning and/with generative models. Recently, I have been interested in the interplay of dynamical systems, causality, and semi-parametric inference. In the past, I was an intern with Jason Hartford at Valence Labs, where I worked on causal representation learning from multiple modalities.

| Nov 1, 2024 | My internship project on matching data from unpaired modalities using propensity scores will appear at NeurIPS 2024! In biology, you can in theory have multimodal measurements of the same cell in biology, but each measurement process is destructive, putting us naturally in a “potential outcomes” setting.
