Biography
I completed my Ph.D in Cambridge at the end of 2002. Immediately afterwards I went to work as a postdoc at the University of New South Wales in the Centre for Quantum Computer technology. After 4 years of living by the beach (and learning how to do microwave-frequency, milli-Kelvin temperature experiments) it was time to come home. So in 2007 I returned to Cambridge to take up the Hitachi senior research fellowship. Since returning, I have built up a research group that focuses on the microwave frequency excitation and measurement of spin-dynamics.
Research
I am interested in studying novel effects due to electron spins in nanostructures: a topic best called nano-spintronics. My research group aims to explore both classical and quantum spin-effects that are relevant for future technologies. In one recent project, we have been investigating current induced torques in spin-orbit coupled ferromagnets, and are now extending this to antiferromagnetic materials. In order to perform this research on magnetic dynamics we had to develop new, ultrasensitive microwave measurement techniques.
