Featured News & Events

'Wisc-e-sota', a Joint UMN-UW Virology Training Grant Symposium was first held on Friday, Sepbember 20th, 2013 at the Uniiversity of Wisconsin-La Crosse, Cartwright Center. This was the inaugural collaborative symposium of the NIH T32-supported virology training programs at the University of Wisconsin-Madison and the University of Minnesota-Twin Cities. Talks and poster sessions were presented by students, postdocs and faculty. The second UMN-UW Virology Training Grant Symposium will be held in the Fall 2014. Details to follow.

The 2014 IMV Symposium will be held on May 12, 2014 and Mark Denison (Vanderbilt) and Bert Semler (UC-Irvine) will be the Keynote Speakers. Click on the link below to register and submit abstracts.
