Thomas Carr, Assistant Professor of Biology

Office Number: Straz B10A
Phone Number: 262-551-5887
Email:    tcarr@carthage.edu
Thomas is a vertebrate paleontologist whose research integrates data of growth and speciation patterns to infer the intrinsic evolutionary processes that explain how unique features in extinct dinosaurs - especially tyrannosaurs - evolved. Thomas earned his Ph.D. in vertebrate paleontology in the Department of Zoology at the University of Toronto, Canada. He joined the Carthage faculty in 2004.

Deanna G. Byrnes, Assistant Professor of Biology

Office Number:
Phone Number: 262-551-
Email: dbyrnes@carthage.edu
Deanna began studying evolutionary biology while earning her B.S. at Cornell University. After working at Abbott Laboratories for six years, she returned to her interests in mammal evolution and tropical ecology to earn her Ph.D. at the University of Wisconsin in Madison in 2005.  She is a rural Wisconsin native, and will join the Carthage faculty Fall 2007, after teaching and researching as a Lawrence University Postdoctoral Fellow in Appleton, Wisconsin.

Dan Choffnes, Assistant Professor of Biology

Office Number: Straz B-6G
Phone Number: 262-551-2374
Email:   dchoffnes@carthage.edu
Dan Choffnes, a developmental geneticist, joined the Carthage faculty in 2006. As an undergraduate, he studied biotechnology through coursework and laboratory research at the University of Illinois at Champaign-Urbana. He continued his training as a National Science Foundation graduate fellow at the University of California at Berkeley, where his Ph.D. research focused on bioinformatics, gene evolution, and developmental genetics. Dr. Choffnes’ Ph.D. dissertation focused on the genetics of stem cell regulation in plants. He maintains research projects in the field of developmental biology and encourages students to pursue independent experimental work.

Dana Garrigan, Associate Professor of Biology

Office Number: Straz B10
Phone Number: 262-551-
Email: dgarrigan@carthage.edu
Dana’s research interests have taken him from the desert southwest of the United States to the rainforest of South America, the New Zealand highlands, and the Galapagos Islands.  Recently, he has been studying butterfly distributions in Mount Rainier National Park to assess the potential impacts of climate change on alpine species.  Dana was an undergraduate at St. Olaf College and earned his Ph.D. in Biology at the University of Utah.  His research interests focus on insects, plants, and their interactions.  He joined the Carthage faculty in 2007.

Tracy Gartner, Assistant Professor of Environmental Science and Biology

Office Number: Straz B10B
Phone Number: 262-551-5803
Email: tgartner@carthage.edu
Starting out as a biology and environmental science major at Coe College, a small liberal arts school much like Carthage, she went on to receive her PhD in ecology from the University of Connecticut. After finishing her degree, she spent two years doing postdoctoral research in Alaska, focusing on the role of the fungal community for decomposition. She joined the Carthage faculty in 2005 as an ecologist and environmental scientist.

Scott Hegrenes, Assistant Professor of Biology

Office Number: Straz 232A
Phone Number: 262-551-6616
Email: shegrenes@carthage.edu
Scott is an ecologist whose interests include evolution, behavior, and conservation. He earned his Ph.D. in Biology from Illinois State University before coming to Carthage in 2001. Scott makes use of the Phil Sander Audubon Sanctuary, the Alice Moody Chapin Arboretum, and the Pike River running through campus as outdoor laboratories for his classes.

Roger Lindberg, Professor of Biology

Office Number: Straz B10D

Email: rlindberg@carthage.edu
Roger earned his Ph.D. in 1974 from the University of Kansas. He spent two years doing postdoctoral research at the University of Kansas Medical Center followed by six years of teaching graduate and undergraduate courses and doing research at the University of Arizona in Tucson. He joined the Carthage faculty in 2000 after 18 years at Abbott Laboratories where he worked on the research and development of diagnostic tests for allergy and infectious diseases.

Patrick Pfaffle, Chair, Associate Professor of Biology

Office Number: Straz 219
Phone Number: 262-551-5516
Email: ppfaffle@carthage.edu
Pat earned his Ph.D. in 1990 from the Medical College of Wisconsin, Department of Biochemistry, where he received the Outstanding Dissertation Award. He taught graduate and undergraduate biology courses at Indiana State University from 1993 until he joined the Carthage faculty in 1997. He has received numerous grants and awards for scientific research, including the National Institutes of Health Academic Research Enhancement Award.

Elaine Radwanski, Associate Professor of Biology

Office Number: Straz 224
Phone Number: 262-551-5865
Email: eradwanski@carthage.edu
Elaine earned her Ph.D. in Genetics and Development at Cornell University in 1995.
