for Lyman Briggs College
- MTH 432 Axiomatic Geometry, Section 001
for the Department of Mathematics
The online course web pages and materials are hosted by MSU's course
management platform, D2L.
Old course pages (before 2018) can be found at the

Research Experience for Undergraduates (REU)
I am one of the organizers of the Summer Undergraduate Research
Institute in Experimental Mathematics
(SURIEM).
This REU in mathematics has been offered each summer since 2010. We
are currentlysupported by the National Security Agency, the National
Science Foundation, and Michigan State University.
In the summer of 2022, we will support 8 REU students.
Information on how to apply appears on the SURIEM web page linked
above. Applications are now open. Applications will begin to be
reviewed on March 1, 2022.
