About Me

I am deeply passionate about understanding the early universe and the intricate processes that shape its evolution. My current research focuses on analyzing multi-field inflation models, quantum loop corrections, and the production of primordial black holes (PBHs). I am also interested in stochastic inflation mechanisms and their implications for cosmological observables.

Stochastic Inflation

Current Work

Investigating stochastic inflation in the USR model and studying its effect on Primordial Black Holes (PBHs). Work in progress.

Primordial Black Holes in Type III Hilltop Inflation

Recent Work

Exploring the production of massive PBHs and the role of quantum loop corrections in hybrid inflation models. We used numerical simulations to study the dynamics of the waterfall phase and its implications for PBH abundance. Our results indicate that the PBHs produced are too small for direct detection, though induced graviational waves could potentially be detected by future proposed detectors, such as the Big Bang Observer (BBO).
