Dave Ansell is the Naked Scientists' Kitchen Science specialist and web monkey. He spent several years nominally as a post-grad physics student at Cambridge University, but spent most of his time AWOL during which he was usually discovered planning and organising science events for kids with student society Cambridge Hands-On Science.
Some time after the grant ran out he took a sideways jump into full-time-and-a-bit public understanding of science. When not at work he... well, he mainly organises science outreach, actually. But sometimes he goes folk dancing.
