Dr. Paul M. Fricke was raised on his family’s row crop and dairy farm located near Papillion, Nebraska where his family continues to farm today. After receiving a B.S. degree in Animal Science in 1988 from the University of Nebraska-Lincoln, Paul went on to complete an M.S. degree in 1992 and a Ph.D. degree in 1996 in Reproductive Physiology from the Department of Animal Sciences at North Dakota State University in Fargo, North Dakota. In 1996, Paul accepted a position as a Postdoctoral Research Associate in the Department of Dairy Science and the Department of Animal Health and Biomedical Sciences at the University of Wisconsin-Madison. Paul joined the faculty in the Department of Dairy Science at the University of Wisconsin-Madison on July 1, 1998, and he was promoted to Associate Professor with tenure in 2004 and to Full Professor in 2009.
Dr. Fricke’s research program focuses on understanding the biology underlying the many reproductive problems presented by modern dairy cattle. Dr. Fricke has authored or co-authored 91 peer-reviewed scientific journal publications, 115 scientific abstracts, and 5 book chapters. He has mentored 13 M.S. and 4 Ph.D. students, and his research program has attracted over $3 million in extramural research grants, contracts, and gifts. Dr. Fricke has twice been invited to serve as a USDA NRI Reproduction Study Section Panel Member. In 2014, Dr. Fricke was awarded a six-month research sabbatical as a visiting scientist at the Teagasc Moorepark Animal & Grassland Research Innovation Centre in Fermoy, Co. Cork, Ireland.
The goal of Dr. Fricke’s extension program is to improve reproductive efficiency of dairy cattle by applying knowledge gained through scientific research to develop practical management strategies and assess new reproductive technologies, and to disseminate that information throughout Wisconsin, the United States, and the world. Dr. Fricke is a sought after speaker for dairy farmer, industry, and veterinary audiences. Since 1997, Paul has spoken to over 500 audiences in Wisconsin and has presented talks at conferences in 34 U.S. states and 6 Canadian provinces. In addition, Paul has been an invited speaker for international meetings in 27 foreign countries spanning 6 continents around the world.
