The Finnegan lab is located on the fifth floor of the Valley Life Sciences Building, in rooms 5151 and 5137 (opposite the skybridge to Life Sciences Addition). I can be reached directly via email (sethf@berkeley.edu) or by phone (510-664-9916).  Like everyone else these days I get a lot of emails and can’t always stay on top of them -if I don’t respond to your initial email, please don’t hesitate to follow up in a few days.
