Overview

I am Professor of Physics and  Head of the Condensed Matter and Photonics group.

My research has the themes semiconductor nanostructures, optical spectroscopy and imaging, with specific emphasis on ultrafast and nonlinear processes, and optical resonators. I combine these themes to provide advances with a scope from fundamental physics, via materials science, to the life sciences.

Research

My research interests are

  1. Quantum optics and ultrafast spectroscopy of semiconductor nanostructures, microcavities, and quantum-dot optical amplifiers.
  2. Application of optical spectroscopy to life-science, focussing on the techniques of coherent anti-stokes Raman scattering (CARS) microscopy, fluorescent resonant transfer, quantitative phase imaging, label-free optical biosensors using microcavities, and statistical analysis of individual quantum emitters such as colloidal quantum dots.
  3. Electromagnetic simulations and the resonant state expansion

Teaching

I hold first- and second-year tutorials, and supervise 3rd and 4th year project students.

In the past years I have been teaching modules in optical microscopy, condensed matter physics, theoretical physics, and quantum optics.

I am supervising post-doctoral fellows and post-graduate students.
