I joined the Computer Science research staff at IBM's Thomas J. Watson Research Center after receiving a Ph.D. in Cognitive Psychology. Since then I have performed research, advanced technology, and management roles, creating award-winning systems in support of interpersonal communications, ubiquitous computing, and web accessibility. I have long been interested in the development of new software engineering metrics and practices and have just completed a multi-year effort in the quantification of productivity in the development of peta-scale parallel/scientific applications. My current research is in the area of contextual computing with a focus on the usability of new programming models.

My technical and professional contributions have been recognized by the Human Factors Society, the Association of Computing Machinery, the British Computer Society, ACM SIGPLAN, and several disability advocacy organizations. I am an ACM Fellow, a member of the IBM Academy of Technology, a Fellow of the British Computer Society, and a Senior Member of IEEE.

I am currently based in New York but travel often on holiday to Scotland, where my wife, Vicki Hanson, is Professor and Chair of Inclusive Technologies at the University of Dundee and where I hold an appointment as an Honorary Professor in the School of Computing.

Here are a couple of photos from our Scotland home in the village of Newport-on-Tay. The first is at the North Sea just a few miles from our house (that's Vicki, Luna, and me walking north towards where the Tay empties into the Sea...or is emptied into depending on the tide). The second is the view from our upstairs loft looking across the Firth of Tay to Dundee.
