My research lies at the intersection of physics and modern machine learning, with a focus on generative models such as normalizing flows, diffusion, and autoregressive models, and their application to physics. I am also interested in theoretical aspects of machine learning, including geometric aspects of deep learning, density estimation, optimal transport, sampling tasks, and modeling of multimodal distributions. Additionally, I explore Bayesian inference techniques, such as Gaussian processes and Bayesian optimization, for solving physics-related problems. These techniques have potential in lattice quantum field theory, soft-condensed matter, quantum chemistry, molecular science, and modern quantum computing.
