It was an interesting four years at Nottingham, and I learned a lot about teaching, which has improved my training courses.
I even learned some things about engineering. It was an opportunity to look at what I knew and how I knew it, so that I could teach it.
I wrote a book about that, and I'm presently working on my second one, on Plant Layout, as well as an entry in Ullmanns Encyclopaedia.
I also have a few articles in press in various Chemical Engineering magazines in the UK and US.
I certainly seem to have picked up a lot more writing work during my time as an academic. It's interesting and enjoyable, if not always that well paid...
