Research Interests

My current research interests are in ultrafast phenomena in condensed matter, instrument development, nanofabrication and computer modeling. The work of my group is typified by experimental studies of materials and devices using femtosecond pump-probe techniques. In particular, we use aspecialization of this method known as time domain terahertz (THz) spectroscopy. We have used this technique to study the dynamics of electrons, phonons and plasmons in semiconductor nanostructures and the propagation of light on microstructured metal-dielectric surfaces and other forms of THz waveguide. We have also developed an ultrabroadband and polarization sensitive THz spectrometer and a fibre coupled THz near field microscope. Current projects are focused on time resolved nonlinear spectroscopy of chacogenides and low dimensional systems using an intense laser ionized plasma source of THz radiation.
