Departmental Colloquia

The GW Department of Physics Colloquia are designed for the non-specialist, including both undergraduate and graduate students, with interest in various aspect of physics and astronomy.

Unless otherwise noted, our colloquia take place on Thursday afternoons from 3:45 pm to 4:45 pm in the Bennhold Auditorium, room 101 of Corcoran Hall. Refreshments are served at 3:30 pm in front of the Bennhold Auditorium.

There are metered parking spaces available on the streets in the vicinity of Corcoran Hall. There is also a visitor's parking garage on H Street, between 21st and 22nd Streets. (Note: Speakers can be reimbursed for their parking fees.) The closest Metro Station is Foggy Bottom/GWU, on the Blue and Orange lines.
