I moved to Brooklyn College of The City University of New York (CUNY) in 2014. My current work aims to improve fundamental understanding of phase transitions between different magnetic states. There are several potential applications of this research, for example in power generation from waste heat and in a new, high efficiency, gas-free cooling device: the magnetic refrigerator. For more information, click the "Research" link or go to the websites of the FP7 projects that I coordinated on behalf of Imperial College: DRREAM (2013 - 2015) or SSEEC (2008 - 2011).
I was a faculty member of the Experimental Solid State Physics (EXSS) section at Imperial from 2009 - 2015. Before joining Imperial College, I was in the Device Materials Group of the Department of Materials Science and Metallurgy at the University of Cambridge, UK. I was also a Director of Studies in Physics at Churchill College, Cambridge for 5 years.
