About Our Colloquium

The Department of Mathematics at CSUSB has a Colloquium series in which we typically we invite five or six speakers each semester. Many of the speakers in fall and winter quarters are guest mathematicians from over Southern California. In spring quarter many of the speakers are our graduate students who are presenting their master's thesis or our undergraduates who are presenting their independent study for the purpose of obtaining departmental honors.  

Historically, colloquia are scheduled on a Wednesday from 2:45-3:35. Refreshments will be provided.  However, with the COVID-19 Pandemic, dates and times may vary.

Pandemic Edition

During the COVID-19 Pandemic, the Colloquium will be held remotely.


For questions about our colloquium, contact our colloquium coordinator, Dr. Jeffrey S. Meyer (
