Matthew J. Potthoff graduated Summa Cum Laude from the University of Oklahoma in 2003 with a B.S. in Biology/Zoology. In 2007, he obtained his Ph.D. in Genetics and Development from the University of Texas Southwestern Medical Center in the laboratory of Dr. Eric N. Olson where he studied muscle development and metabolism. Between 2007-2012 he performed a Howard Hughes Medical Institute (HHMI) Postdoctoral Fellowship in the laboratories of Drs. David Mangelsdorf/Steven Kliewer and Dr. Shawn Burgess where he examined the role of endocrine fibroblast growth factors in regulating hepatic metabolism. In July 2012, Dr. Potthoff moved to the University of Iowa to become a member in the Department of Pharmacology and the F.O.E. Diabetes Research Center. His primary research interests are on the role of liver-derived factors, or hepatokines, in the regulation of systemic glucose and energy homeostasis. Matt’s hobbies include fishing, playing with the family, and throwing the ball with his dog, Cooper.
