My research focuses on the physics of the early Universe, particularly cosmic inflation and the nonlinear dynamics of preheating and reheating. I use high-performance three-dimensional lattice simulations to capture the fully non-linear evolution of these epochs, and I am also exploring quantum-computing approaches to cosmological drift-diffusion equations. A central aim of my work is to connect the dynamics of the primordial Universe and the primordial dark ages with observable signatures such as primordial gravitational waves, primordial black holes, and targets for particle physics searches, mapping the theoretical landscape for the next era of cosmological and gravitational-wave exploration.
