I am a structural geologist based in the UK. I did a Masters on the Fracture Mechanics of quartz and a PhD on the formation of shear zones. I continued doing research, particularly on the Devonian basins of Norway and Scotland, until my funding ran out. I started doing consulting work while waiting for that elusive permanent university post to come along. 33 years later I'm still consulting, but I have given up waiting. I've worked mainly on nuclear waste disposal problems and for the oil industry, so no environmental issues at all.
I started contributing to Wikipedia in July 2006, concentrating on adding content to structural geology . I started on Wikimedia commons in March 2008, although I had already created and uploaded a bunch of images to Wikipedia, I just hadn't thought to bring them here. I'll be copying my existing images over when I get a moment,
