UMass Department of Psychiatry holds Grand Rounds most Thursdays from noon to 1 in the Lazare Auditorium on the first floor of the Medical School Building, 55 Lake Ave N, Worcester, MA.
Here’s a link to their site. It’s open to the public. Just walk in like you are supposed to be there.
Here is a list of some great talks.
Many of them were videotaped. You can find them here. For those of us not part of the Umass computer system, there is a temporary username and password available at the desk of the Med School Library. That password works on their computers and on my computer at home. The password changes about once a month.
