Research

My research lies at the interface of machine learning and physics. I develop deep-learning and Bayesian methods that build physical structure, such as symmetries, conservation laws and sparsity, into the model, to solve ill-posed inverse problems and learn dynamical systems from data with quantified uncertainty.

AI for cell mechanics: traction force microscopy

Traction force microscopy infers the forces that cells exert on an elastic substrate, an ill-posed inverse problem. I developed Bayesian regularization methods released as open-source software, and now build hybrid Vision Transformer + U-Net networks that use cell-type metadata and generalize across scales and noise levels.

Physics- and symmetry-constrained deep learning for PDEs

Neural surrogates accelerate numerical solvers but tend to accumulate errors over long rollouts. I design group-equivariant layers for staggered grids that enforce symmetries and conservation of mass and momentum as hard constraints, giving accurate and stable predictions of fluid flows and real ocean currents.

Bayesian machine learning for discovering governing equations

Identifying governing equations turns data into interpretable models. My sparse Bayesian learning method (ATSBL) selects the relevant terms of ODEs, PDEs and SDEs with uncertainty on every coefficient, and an active-learning feedback loop makes the inference of stochastic dynamics more data-efficient.
