Mr Andrew Gow
Summary
I am a Research Fellow in the Institute of Cosmology and Gravitation, working with Professor David Wands. My research focuses on stochastic inflation, and its relation to the formation of compact objects such as primordial black holes.
I graduated from the University of Sussex with an MPhys in 2017, where I remained to do a PhD entitled "A history of the universe in primordial black holes" with Dr Christian Byrnes, which I completed in 2021.
