Academic Research

Before venturing into deep learning, I did a PhD in Mathematics focusing on the intersection of geometry and string theory.

String theory has, over the past few decades, been a curious venue for a profound interaction between mathematics and physics. The efforts to formulate a fundamental quantum theory of gravity have led several branches of pure mathematics to make an appearance in physics. Most notably, geometry in its various forms has started to take on a prominent role.

My research focused on the geometric objects—higher-dimensional shapes—that appear in string theory and how their properties manifest in the physical theories they are associated with. Usually with opaque names like G2 manifolds or GK geometries, these shapes are often of independent mathematical interest. What makes them especially exciting is the fruitful interplay of mathematics and physics that is present.
