I am creating and teaching a course called "Supersymmetric Methods in Theoretical Physics" (see here).
The basic idea is to give a course in supersymmetry that emphasizes the simplest settings in which general principles emerge rather than studying SUSY as an extension of the Standard Model (although this topic is interesting in its own right!). Some of the areas to be covered include the Witten index, N=2 SUSY quantum mechanics (SQM), N=(2,2) SQM, and various applications (e.g., to understanding dynamics of quantum mechanical systems, Berry's phase, etc.). The last part of the module will cover 3D SUSY theories and some of the remarkable dualities that emerge.
I am also a supervisor for 2 MSci projects and 1 BSci project. The general area of study is the physics of anyons.
My current research interests include:
• Various aspects of boundary conformal field theory (BCFT) and CFTs with defects; see here for a recent workshop I co-organized with Andy O'Bannon on the topic
• Non-perturbative aspects of Superconformal Field Theories (SCFTs) and Supersymmetric Renormalization Group flows in various dimensions
• Conformal manifolds and exactly marginal deformations of SCFTs
• Relations between conformal manifolds and moduli spaces of vacua
• Emergent / accidental symmetries in Quantum Field Theory (QFT)
• Hidden operator algebras in QFT
• Relations between Topological Field Theories and CFTs
• Understanding topological and analytic properties of the space of QFTs
• New microscopic models for CFTs in various dimensions
• Hitchin Systems, M5 branes, and SCFTs in 3D and 4D
