Research interests

Quantum field theory, conformal field theory, supersymmetry, and string theory. Algebraic structures occurring in each of the above.

Teaching

In the 2025-2026 academic year I am lecturing B7.3 Further Quantum Theory. In the past I have also lectured String Theory I for the Master's programme in Mathematical and Theoretical Physics, the Part A Special Relativity short option, and a graduate course on vertex operator algebras.

At St. John's I tutor physical applied courses, including Geometry, Dynamics, Differential Equations, Part A Geometry, and Projective Geometry.
