On Friday, Nov. 30, the Martinos Center celebrated two landmark events for its MEG program: MEG Core director Matti Hämäläinen’s promotion to full professor of radiology at Harvard Medical School and the renaming of the Center’s MEG facility in honor of David Cohen, the Martinos faculty member and “father of MEG.” Check out photos from the event below.
