My research interests are in Algebra/Group Theory. I have made available a few of my recent reprints and preprints. You are welcome to browse and take what you want.


This year's ALGEBRA VIGRE seminar is on Cohomology of Finite Groups. A collection of relevant papers may be found here . I have also posted there a GAP program to compute 1-cohomology for finite groups, and to compute extensions of KG-modules.


  • In Summer 2009 I led a Research Experience for Undergraduates (NSF - REU) in , (0,2)-Graphs, Root Systems and Cohomology
