I am a Senior Lecturer Emeritus in the Dept. of Computer Science at the University of Toronto. "Emeritus" means I'm retired. "Senior Lecturer" means that before retirement I was a faculty member in the teaching stream (as opposed to the research stream).
The DCS grading program documentation is now at http://www.cdf.toronto.edu/~clarke/grade.
I still look after those programs, so please do ask me if you wonder about how to use them. There's also a succession plan, so there'll be someone to ask when I'm gone — but I'm not telling you who the "someones" are, because they're hoping it never happens. Me too, actually.

I share an office, room 3250 in the Bahen Centre at 40 St. George Street. However, you should contact me beforehand instead of just dropping in, since most days of the week you won't find me in.
