Ian A. Morrison

I am currently a Simons Postdoctoral Fellow at DAMTP. My research concentrates on the marriage of quantum field theory and general relativity. I am particularly interested in the structure of perturbative quantum gravity, cosmological perturbation theory, dS/CFT, and holographic entanglement entropy. I also enjoy teaching and have previously been a supervision leader for the Tripos Part III courses Advanced Quantum Field Theory and General Relativity.
