I’m a postdoc at MIT CSAIL in Polina Golland’s Medical Vision Group where I work on representation learning frameworks for zero-shot generalization to entirely new tasks, biomedical contexts, and datasets. I want to build machine learning methods that biomedical domain experts can use as-is without needing to retrain or adapt to their use-cases.

I got my Ph.D. from NYU under Guido Gerig at the VIDA Center where I worked on generative models and inverse problems in medical image analysis contexts.

I’m always happy to talk, feel free to reach out if our interests overlap!

Research Overview

I tackle the pervasive lack of biomedical training data and supervision to create models that generalize to new biomedical settings with minimal to no new training data.

Recent Updates

  
10/24New work! Using random compositions of templates to drive a self-supervised objective, we get entirely general-purpose representations that yield SOTA 3D registration and segmentation.
09/24New at NeurIPS 2024: fast equivariant modeling of spatio-spherical data leads to SOTA neuronal fiber tracking in diffusion MRI.
07/24I’ll be an area chair for ML4H 2024.
06/24Our new work (led by Benjamin) in IEEE TMI shows that intensity-canonicalization greatly improves SE(3)-equivariant rigid tracking in volumetric data.
02/24At CVPR 2024: Our new work (led by Vivek) leverages differentiable rendering, se(3) lie algebras, self-supervised geodesic pre-training and more to get sub-millimeter accurate 2D/3D rigid registration, all in about a second.
