About Our Colloquium

The Department of Mathematics at CSUSB has a Colloquium series in which each term we invite experts to come in and share interesting math ideas, problems, and applications.  These talks are intended for a more general audience, not just mathematicians, and all are welcome.  Typically about half of the audience is comprised of our math undergraduates.  

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