I spent last night in Philadelphia lecturing at the University of Pennsylvania's graduate program in criminology. I've done this for the past three years at the request of Laurie Robinson, the head of the program. I met Laurie in the 1990s when she served as the head of the Office of Justice Programs in the Clinton Justice Department. She has also served as an adviser to the Obama campaign on criminal justice issues. I think she (and Larry Sherman) have put together an interesting program at UPenn -- anyone interested in pursuing graduate work in the area should check them out.
