Research interests span cosmological numerical methods, dark matter dynamics, perturbation theory, galaxy cluster physics, and applications of deep learning to astrophysical simulations. Recent work emphasizes non-Gaussianity in primordial conditions, relativistic effects on cosmic structures, and differentiable cosmological frameworks.
2023–2025 publications highlight advancements in N-body simulations, hydrodynamical galaxy formation, and uncertainty quantification through denoising diffusion models. Key themes include the interplay between baryonic and dark matter, tidal effects in structure formation, and computational tools for cosmological research.
