**I AM CURRENTLY ON LEAVE OF ABSENCE AT SUNY BUFFALO, MY MOST UP TO DATE WEBPAGE IS

here

I  am an associate professor at the University of Toledo mathematics department. My office is UH2010G and my office phone is 419-530-2973.

Previous to coming to Toledo I was an NSF postdoctoral fellow at the University of Georgia math department.  My senior scientist and collaborator was Professor  Dan Nakano .

In  2001 I  completed my Ph.D at the University of Chicago math department , working under the supervision of Professor  Jon Alperin .  My research focuses on the modular representation theory of symmetric and general linear groups.

My CV:   Here is my CV as of October 2006.
