Areas of Expertise

  • I use the methedology of perturbative quantum field theory to investigate a variety of problems including the understanding of the interactions in Gauge Theories and in examining the perturbative consistency of possible theories of Quantum Gravity.

Teaching

  • PH-104 Astronomy and Cosmology

    This module is a basic introduction to Observational Astronomy and Cosmology. It will be given in a non-mathematical style and is intended to inspire and motivate students of any discipline at an early stage in their studies. Opportunities will be given for making practical astronomical observations.

  • PH-227 Mathematical Methods in Physics II

    This module introduces further mathematical methods used in Physics, especially complex variable theory, Fourier analysis, and their applications.
