Biography

Steve Asmus is H.W. Stodghill, Jr. and Adele H. Stodghill Professor of Biology and Biochemistry & Molecular Biology. He has taught in the biology and biochemistry/molecular biology programs since 1996. He received the Kirk Award for Excellence in Teaching in 2001 and again in 2016, and was named a Centre Scholar in 2011. Prior to joining the college, he held a postdoctoral fellowship in the Department of Neurosciences at Case Western Reserve University.

Asmus has special expertise in the field of developmental neurobiology, which focuses on how the brain develops. He describes his research as a study of the development of neurons, which are specialized types of cells found in the nervous system. The neurons produce chemicals known as neurotransmitters that make it possible for the neurons to communicate with each other.

Asmus is interested in how neurons produce the correct neurotransmitter during development. He has analyzed the neurotransmitters produced in developing sympathetic neurons, addressing the question of whether different target tissues influence this “decision” process during development.

Currently, Asmus is studying the neurotransmitters that are produced in the cerebral cortex of the developing and adult brain to examine whether some cortical neurons may change the neurotransmitter that they produce as they mature. Asmus uses a variety of cell staining and microscopy techniques in his laboratory research.

Asmus encourages Centre students to collaborate with him on research. His recent collaborators, all biochemistry and molecular biology majors, include Kaylind Batey ’17, Serena Gale-Butto ’17, Shannon Murray ’17, and Lexie Szalanczy ’18.

Asmus has published his research in journals including the Journal of Chemical Neuroanatomy (2016), Brain Research (2008 and 2011), and the Journal of Neuroscience (2000). Asmus co-authored these research articles with numerous student collaborators.

Asmus earned a B.S. degree from Cleveland State University and a Ph.D. from the University of Michigan, and conducted a postdoctoral fellowship in neuroscience at Case Western Reserve University before coming to Centre.

Biography

Stephanie Dew is a professor of biology at Centre College, where she has taught since 1994. Dew was named a Centre Scholar in 2009, and has served as chair of the biochemistry & molecular biology program. Her teaching assignments are concentrated in biochemistry and molecular biology, including courses in biomolecular architecture and biochemical pathways.

Dew has pursued research since her own undergraduate days at Centre, focusing on the proteins and enzymes required for the transport and metabolism of vitamin A, especially in freshwater fish. In 1997, she received a grant from the Teagle Foundation for research at King’s College of the University of London. Dew worked with a team investigating the role of vitamin A in development.

At Centre, Dew seeks to involve her students in research. In her first four years at the college, she has directed seven independent study-research projects, including two students chosen for Centre’s prestigious John C. Young Scholars program. Brad Eilerman, a Centre student who collaborated with Dew on a summer research, won first place in the undergraduate division of the Kentucky Academic of Science for his presentation of the research.

An innovative teacher, Dew has been at the forefront of efforts to obtain and appropriately use technology in Centre’s science classes.

She earned a B.A. at Centre, graduating Phi Beta Kappa, and completed a Ph.D. at Vanderbilt University, where she was a University Graduate Fellow.

Biography

Amanda Falk graduated with a B. S. (Honors) in Biology from Lake Superior State University, performing a senior thesis on molecular and morphometric sexing of bald eagles and related species. She received her M.S. and Ph.D. in Geology from the University of Kansas, studying avian paleontology and ichnology—trace fossils—as well as anatomy and behavior of modern birds. During this time she began research in China and South Korea, supported by a U.S. Fulbright Grant from 2011-2012 that provided the opportunity to perform extensive research in China.

She has expertise in paleobiology, evolutionary biology, functional morphology, and fossil behavior. Her current research interests are studies of fossil avian anatomy, avian ichnology (the study of preserved behavior known as trace fossils—footprints, burrows, etc.), comparative studies of modern avian anatomy, studies of modern avian footprint production and tracemaking behavior, laser-stimulated fluorescence of fossils, and paleobiodiversity and mass extinction.

Biography

Anne Lubbers is professor of biology at Centre College, where she has taught since 1993.

A plant ecologist, Lubbers has special expertise on factors affecting seed production. Her work has been published in professional journals, including the American Journal of Botany and Ecology.

Lubbers provides her Centre students opportunities for collaborative research. For the last five years she has studied reproductive success in wild ginseng. One or two students work with her each summer as they visit eight forest populations throughout Kentucky of this increasingly uncommon species. One of those students, Karen Trowbridge, subsequently was awarded third place in the biology poster competition at the joint annual meeting of the Tennessee and Kentucky Academy of Sciences in the fall of 2001. This summer Lubbers will continue the process of studying how soil conditions, sunlight, and pollination affect the plant’s ability to produce seed.

Lubbers says of such field work for students: “Whatever field our students go on to pursue, they gain some really important basic skills in this program—how to be organized in collecting data, the importance of being careful when recording numbers or doing lab work, how to interpret the information obtained, how to use a computer for graphing and—especially—how to think logically and concisely.”

Lubbers is a member of the Botanical Society of America, the Kentucky Native Plant Society, the Ecological Society of America, and the Southern Appalachian Botanical Society. She holds a B.S. from the University of Wisconsin-Green Bay and a Ph.D. from Duke University.
