Expertise

Representation theory. Calabi-Yau geometry. String theory.Profile

My research lies at the interface between algebra, geometry, and physics. I study the interplay between representations theory, Calabi-Yau geometry and string theory. Intuitions and insights from one theory can often manifest themselves in a powerful and sometimes surprising ways to help solve problems in another theory. WebpageCourses Taught
