Research Interest

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 a particular specialization 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. We have also developed an ultrabroadband and polarization sensitive THz spectrometer and a fibre coupled THz near field microscope. Current or planned projects involve near THz field imaging of microstructured waveguides, establishing techniques to measure THz circular dichroism in biomaterials, the development of a cheap THz instrument for assessing drought stress in crops, THz electro-chemical sensing and femtosecond studies of graphene.
