I am a theoretical physicist. I received my AB in Physics from Harvard University and my PhD in Physics from Princeton University. I was a postdoc at CERN, Rutgers University, and The University of Chicago before joining the academic staff at QMUL.
In 2017-18, I created a course called "Supersymmetric Methods in Theoretical Physics" (see here). I taught it also in 2018-19 and will teach it again in 2019-20.
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 have also supervised 4 MSci projects, 1MSc project, and 3 BSci projects. The general area of study is the physics of anyons and emergent phenomena.
• Various aspects of boundary conformal field theory (BCFT) and CFTs with defects. I have organized several workshops on these topics: a 2017 workshop at Chicheley Hall sponsored by the Royal Society, a 2019 workshop at the Perimeter Institute. I am also organizing an upcoming workshop in 2020 at the MITP in Mainz.
• 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
