Colloquium and Seminars

See our Events section for upcoming Colloquia and Seminars.


The Colloquia of the Department of Mathematics are intended to be a vehicle for invited speakers to communicate to the entire department significant new developments in their fields of research, in a manner accessible to a broad mathematical audience. Graduate students and visitors are particularly welcome.  A Colloquium is normally held on Thursday afternoon at 4:15pm in Cockins Hall 240.  It is preceded by a tea reception at 3:15pm in Math Tower 724, and then followed by a dinner. 

Previous colloquia can be viewed on the OSU Math Youtube Channel.

Welcome Seminar

On Thursdays when colloqiua are not organized, the department hosts a Welcome Seminar. The goal of Welcome Seminar is to give an opportunity to new postdoctoral fellows and tenure track professors to introduce themselves to their colleagues. The talks are intended to be non-technical and accessible to graduate students as well. Welcome seminars are held on Thursdays when a colloquium is not organized at 4:30pm in Cockins Hall 240 and preceded by a tea reception at 4:00pm.


The Mathematics Research Institute provides financial support for off-campus speakers in the research seminars of the Mathematics Department.
