Research Themes

My research develops principled computational frameworks that bridge physics-based models, statistical inference, and machine learning.

Plug-and-Play Priors (PnP)

The Plug-and-Play Priors framework enables flexible integration of powerful denoising algorithms as Bayesian priors in inverse problems. Adopted by 100+ research laboratories worldwide and implemented in Samsung Galaxy smartphone fingerprint sensors.

Consensus Equilibrium

Multi-agent optimization framework for modular integration of disparate sources of expertise. Led to a $1.2M NSF research grant.

Latent Space Geometry for Explainable AI

Using differential geometric tools (Fisher-Rao metric) to diagnose failures in representation learning networks.

Privacy-Preserving Machine Learning

Privacy-preserving face identification using generative neural networks. Awarded Wells Fargo Medallion for Most Innovative Patent (2020).
