Research Interests

My interests range from String Phenomenology to Quantum Field Theory and Quantum Gravity more generally.

String Phenomenology attempts to generate testable predictions from String Theory (or Quantum Gravity more generally). Doing so often pushes the limits of what is known about String Theory and suggests new research directions in abstract Quantum Field Theory and Quantum Gravity.

Recently, I have worked extensively on the Weak Gravity Conjecture, a class of hypotheses about the spectrum of charged particles in quantum gravities with interesting implications for phenomenology.

Another focus of my recent research is electromagnetic duality in gauge theories with minimal supersymmetry, related to D-brane physics in string theory.
