I commenced a PhD in Physics at the Nanophotonics Centre at Cambridge with Professor Jeremy Baumberg in January 2009, and I'm loving it. My topic is "Nanovoid Plasmon-Enhanced Photovoltaics" - using some new physics to make solar cells more efficient. I think one of the biggest challenges of our generation is to understand our planet's resources and develop ways to live with them sustainably. I'm enjoying researching a means of electricity generation that can be safe, clean and decentralised.
