New website!My website has been moved to http://www.cs.toronto.edu/~david.
My office is located in BA4260. I'm usually in my office during the day - if you see the lights on, please feel free to knock! (But for an extra guarantee, send me an email to set up an appointment.)
My email address is david at cs dot toronto dot edu. Please include a descriptive subject line if you try to contact me - otherwise I can't guarantee the co-operation of my spam filter.
