Research
I'm interested in deep generative models, optimal transport, and Bayesian deep learning.

NeurIPS workshop on Bayesian Decision-making and Uncertainty, 2024
Consider time series whose dynamics can be described by discrete latent states. Our approach models the latent trajectory as the solution to a multi-marginal Schrödinger bridge problem in a discrete state space. The proposed methodology enables trajectory reconstruction and extrapolation for irregularly-observed time series data in high-dimensional state spaces.

We introduce a dynamic formulation of conditional optimal transport, and incorporate it into the flow matching framework. We showcase the method on challenging Bayesian inverse problems.
