My career in science started with a degree in Natural Science at the University of Cambridge specialising in quantum chemistry. Then I did a PhD, also at Cambridge, in solid state photochemistry. To my surprise my PhD is listed on the web as indeed are the papers from my PhD work, even though the World Wide Web didn't exist at the time!

After finishing my PhD I worked as a colloid scientist for Unilever Research. Now I'm getting old and grey I answer questions on the Physics Stack Exchange to stop my brain from atrophying.

I'm mostly interested in general relativity though I'll have a go at anything related to quantum mechanics as well. Next on my bucket list is to learn quantum field theory though that is turning out to be a challenge! I hang around in the chat room and I'm happy to answer questions there as well. Just ping me if you want my attention.
