Bio

Bartholomew Pederson received his PhD at the University of North Dakota School of Medicine and Health Sciences where he investigated the regulation of glucose-6-phosphatase in liver. He completed a postdoctoral fellowship at Indiana University School of Medicine-Indianapolis where he examined glycogen synthase regulation in yeast and the role of muscle glycogen synthase in transgenic and knockout mouse models. Dr. Pederson’s most recent research uses genetically modified mouse models to study the role of glycogen in health and disease.

Titles & Appointments

  • Adjunct Associate Professor of Biochemistry & Molecular Biology
  • Education
    1998 PhD University of North Dakota
    1992 BS Bemidji State Unviersity
  • Research
    My laboratory is broadly interested in glucose metabolism. Specifically, we are studying the role of the storage form of glucose, glycogen, in various tissues.

    We have mice genetically engineered to lack or overaccumulate glycogen in several tissues. We are studying these animals to better understand the importance of glycogen in organ development and function, as well as in diseases such as diabetes and epilepsy.
