Research topics
My research connects machine learning with scientific computing. I am particularly interested in learning from partial observations, representing physical structure, and evaluating models through reproducible experiments.
Partial observations & neural operators
Many scientific systems are observed through sparse sensors or incomplete measurements. I study neural operators and inference methods that recover full fields from these observations, and how their predictions change across resolutions and observation patterns.
PartialObs–PDEBench
A benchmark for sparse, irregular, sensor-style, and masked PDE observations. It brings together datasets, observation configurations, and evaluation metrics for neural operators, diffusion models, and physics-aware baselines.

Predictive representation learning
I investigate joint-embedding predictive architectures for scientific data, including student–teacher learning, latent full-field prediction, and representations across spatial resolutions.
Physics-aware generation & optimization
I develop sampling and optimization methods that incorporate physical constraints, combining diffusion models, simulated annealing, and reinforcement learning.

- RL-QESA. Reinforcement-learning quasi-equilibrium simulated annealing.
- Structure-aware dynamics. Hamiltonian and symplectic learning, including Kolmogorov–Arnold representations and learning dynamics from position-only observations.

Molecular generation & LLM-guided search
My work in molecular design combines generative modeling and optimization under structural and validity constraints.
ORACLE: LLM-guided molecular optimization
LLM-proposed molecular edits are combined with simulated annealing for multi-objective structure-based drug design. Evaluation considers docking, QED, synthetic accessibility, diversity, and Pareto trade-offs.
