My research interests are

Quantum optics and ultrafast spectroscopy of semiconductor nanostructures, microcavities, and quantum-dot optical amplifiers.
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.
Electromagnetic simulations and the resonant state expansion

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.
