About

Background

Dr Yang-Hui He studied at Princeton University, where he received his Bachelor of Arts in Physics, with a Certificate in Applied Mathematics and a Certificate in Engineering, Summa cum Laude. He then obtained a Certificate in Advanced Mathematics (Tripos) at the University of Cambridge, with Distinction. He went on to receive his PhD in theoretical and mathematical physics from MIT. Yang continued with postdoctoral work in the University of Pennsylvania before joining Merton College, University of Oxford as the FitzJames Fellow in Mathematics and then the UK STFC Advanced Fellow in theoretical physics. Yang joined City in 2010 as Reader in Mathematics and was concurrently awarded the YangTze Chair Professorship at NanKai University by the Chinese Ministry of Education.

Research

Yang is a mathematical physicist working on various interfaces between geometry and theoretical high energy physics. He is particularly interested in aspects of algebraic geometry in application to, and interacting with, gauge theory as well as string theory, such as Calabi-Yau manifolds, holographic correspondences and string phenomenology. He also has interests in the dialogue between number theory, graph representation theory and gauge theories.
