Seminars

We hold, on a regular basis, weekly seminars every Wednesday at 1:00pm. The format of the meetings, which typically take place in the 2nd floor seminar room of the Physics Bldg, is rather informal and it ranges from open discussions to presentations by members of the group or visitors. If you are interested to lead one of these meetings or give a seminar with your recent results, or you would simply like to visit us, please contact Dr. John Antoniadis.
