Martian Death Rays After graduating from The Queen's College, Oxford, in 2002 with a degree in Biological Sciences I moved to University College London for a four year combined MRes-PhD programme with the CoMPLEX (Centre for Mathematics & Physics in the Life Sciences and Experimental Biology) department. I was awarded my doctorate (thesis available here) in 2008, which has been reprinted by academic publishers as Martian Death Rays. I'm now working in the Centre for Planetary Sciences, researching in the field of astrobiology and the possibility of microbial life surviving in the surface dust of Mars in the face of the constant rain of radiation from space. I use a combination of computer models to simulate the penetration of space radiation and laboratory experiments on bacteria I've isolated from Antarcica and signs of life that might remain on Mars.

In 2003 I was awarded second prize in the THES / OUP science writing competition for an article on the parallels between the structure of language and proteins, and in 2004 I won second prize in the Daily Telegraph / BASF Young Science Writer Award and first place in the Royal Astronomical Society university science writing competition. My first book, Life in the Universe: A Beginner's Guide, was published by Oneworld Publications of Oxford in April 2007, and my children's illustrated science book Tourist's Guide to the Solar System came out with Dorling Kindersley in February 2012. In 2009 I was a national finalist in the FameLab competition to find the new faces of science communication (watch my TV showreel video here).

I give regular talks at schools and science festivals (and even aboard cruise ships!), and also act as an 'ambassador' for science through the NOISE (New Outlooks in Science and Engineering) programme. If you would like to book me to speak at your school please see my entry on the ScienceLive database of science events.
