I can probably answer most general questions about the history of science, technology and engineering from ancient to current; if I don't know a specific answer I can probably refer a questioner to an appropriate source. I have done original research in the history of computing and in British science and engineering in the 17th, 18th and early 19th centuries.
I am a PhD student at the University of York, writing about the carrying trade in the 18th century; my previous work at the university includes the early history of plate railways. I have taught courses in the history of science and engineering at York and other universities, and have presented several papers on various subjects in this field at academic conferences. I am also a practicing civil engineer.
