I work on generative models for visual content and study how machine learning can represent, predict, and control complex physical systems. My research has focused on the intersection of deep learning and computational physics, especially spatiotemporal dynamics governed by partial differential equations.

Across my Ph.D., I developed architectures that incorporate physics-based structure directly into learning systems, with applications spanning turbulence modeling, scientific machine learning, diffusion models, and reinforcement learning for nonlinear dynamical systems.

Focus Areas

My work sits at the overlap of generative AI, computational physics, and scientific machine learning. I am interested in models that do more than fit data: they should encode structure, respect dynamics, and generalize across regimes that matter in practice.

Recent topics include latent diffusion for spatiotemporal turbulence, physics-preserved neural architectures, operator-aware learning for PDE systems, and scalable reinforcement learning for expensive fluid-structure interaction environments.
