I'm a fourth year PhD student at Cornell University's Laboratory for Elementary Particle Physics, Institute for High-Energy Phenomenology.

Adviser: Liam McAllister

Research Interests

I am interested in building inflation models inspired by string thoery and studying their observational signatures. I'm also interested in studying the landscape.
