Staff Bios

Bob Howe

Robert Howe, Director

Mary Ann Cofrin Hall 212B 920.465.2272

Bob Howe is the founding Director of the Cofrin Center for Biodiversity and Barbara Hauxhurst Cofrin Professor of Natural Science at UW-Green Bay. He has been a faculty member in UWGB’s Department of Natural and Applied Sciences since 1984, where he has taught courses ranging from introductory environmental science to advanced undergraduate and graduate courses in biology and ecology. In addition to administrative responsibilities with the Cofrin Center for Biodiversity, he maintains an active research program involving bird population dynamics, northern forest ecosystems, and the ecology and conservation of Great Lakes coastal wetlands. Bob is author or co-author of more than 50 scientific publications, including The Atlas of the Breeding Birds of Wisconsin and papers in international journals like Ecology, Evolution, Biological Conservation, and Journal of Wildlife Management.    

A proud father of three boys, Bob enjoys biking, nature-watching, and traveling to parks and natural areas around the world with his family. He and his wife, Dr. Amy Wolf, lead international travel courses to Panama and (upcoming in 2013) Australia. Bob also is a youth soccer coach and an avid Green Bay Packer fan.    

Vicki Medland.

Vicki Medland, Associate Director

Mary Ann Cofrin Hall 218E 920.465.2342


Dr. Medland works cooperatively with the Director to ensure that the center is achieving its mission of education and research. She works closely with staff and partners involved in various outreach projects including the web and social networking sites, K-12 and citizen science programs. Vicki leads the Panama research course with her husband Mike Draney in alternate years and teaches courses in environmental science. She is active with the Baird Creek Preservation Foundation and the Ridges Sanctuary where she serves on the board of directors. She is also the coordinator for the NAS Heirloom Plant sale.

Like so many kids, her dream of becoming a marine biologist was stymied by a midwestern life-style. Fortunately, guided by a dedicated professor at UW Madison, she eventually became an evolutionary biologist who focused on studying the life history and behavior of organisms living complex life-cycles in temporary pools. At home she dabbles in gardening, cuisine, writing, and scientific illustration.

Erin Gnass.

Erin Giese, Data Manager

Mary Ann Cofrin Hall 124A 920.465.2545

I recently defended my graduate thesis and graduated in May 2012 with a Master of Science in Environmental Science and Policy (Ecosystems Studies emphasis).  I earned my undergraduate degree at the College of William and Mary (Williamsburg, VA) with a major in Mathematics and a minor in Environmental Science and Policy. My current job is Data Manager. I am primarily responsible for archiving, managing, and organizing the Biodiversity Center’s scientific data collections, including UWGB’s natural history collections from the Richter Museum and Herbarium, Nicolet National Forest Bird Survey, and other research projects. Through small training sessions, I assist students in learning how to enter and manage their own data collections, particularly for Cofrin Student Research Projects.  For the Biodiversity Center, I handle relationships between UWGB and other organizations involving data-sharing agreements and policies. I also work with other organizations in managing and updating the Birder Certification Online, which is a website designed to test visual and audio identification skills of birders.

I am also working through the summer of 2012 as a Field Crew Leader for the Great Lakes Coastal Wetland Monitoring Program (GLCWMP). I select survey sites, coordinate field crews, help field assistants, plan survey trips, conduct amphibian and bird surveys, and enter and manage collected data. I truly love organizing and managing data, working on conservation projects, working with others, and conducting field work, which is why I chose these jobs. I really enjoy attending and helping with the annual Nicolet National Forest Bird Survey by conducting bird surveys with birders from across the State of Wisconsin.

From 2007-2014 he developed and co-taught a course on Remote Sensing and GIS with Dr. Kevin Fermanich. See his blog for GIS coaching tips and resources.

Mike earned a BS in Mechanical Engineering from Marquette University in 1969 and worked as a process engineer for plant design and construction projects for many years, earning his Professional Engineer's license from the State of Wisconsin along the way. Mike was looking to change direction when he enrolled in UWGB's master's program in Environmental Science and Policy. He credits Gary Fewless' Field Botany class for turning him on to the natural world. Dr. Niedzwiedz' Introduction to GIS course with revealing what his brain is really wired for. When he is not glued to a computer, he can be found building or fixing stuff, walking in the woods or on the road to a concert or folk festival. Once in a while he gets to tag along on a really cool field expedition.
