(In reverse chronological order)
Since August 1993 I have worked at Sun Labs which morphed into Oracle Labs in 2010. Look here for more details.
Before that I was a post-doctoral researcher and research fellow at the Department of Computer Science of the University of Manchester, where I worked on the Mushroom project, investigating hardware and software implementations of dynamic object-oriented languages. I also developed and taught industrial courses, in Smalltalk, C, UNIX, object-oriented methods and other topics for the PEVE Unit.
From 1984 to 1987 I studied for my Ph.D. in the Semantics of Object-Oriented Languages, also at the Department of Computer Science of the University of Manchester. Here's a list of my publications from that work.
My M.Sc., obtained in 1984, was about Implementing Smalltalk-80 on the ICL Perq.
You can find me on LinkedIn (I'm no longer on FaceBook).
