Brief biography

Mark Sandheinrich, PhD is Professor of Biology and Dean of the College of Science and Health at the University of Wisconsin-La Crosse. He earned a PhD and MS in Fisheries Biology from Iowa State University and a BS in Ecology, Ethology & Evolution from the University of Illinois at Urbana-Champaign. He has 30 years of experience and more than 40 publications on aquatic ecology and on the effects of contaminants in aquatic systems. He and his students conduct research on (1) the bioaccumulation, maternal transfer, and reproductive effects of methylmercury exposure in fish; (2) bioaccumulation of methylmercury in aquatic food webs and (3) identification of controls on ecosystem sensitivity to mercury in atmospheric deposition.

THANK YOU to the many staff and faculty who greeted students and their families at the Verification Tent during Residence Life Move In Week. These welcoming faces helped ensure those who are vaccinated are recorded as such and those who are not vaccinated had completed a negative COVID test prior to move in. We could not have completed this large task without their assistance. They have helped keep our community healthy and contributed to the campus-wide endeavor of welcoming students back to campus.
