Raisz Professorship in Bone Cell Research School Medical School Department Internal Medicine | Charles and Jane Pak Center for Mineral Metabolism and Clinical Research Graduate Programs Genetics, Development and Disease Biography Download Curriculum Vitae Courtney Karner, Ph.D., is an Associate Professor in the Department of Internal Medicine at UT Southwestern Medical Center and a member of the Division of Nephrology in the Pak Center for Mineral Metabolism and Clinical Research. Originally from Lincoln, Nebraska, Dr. Karner holds a bachelor's degree in biology from East Central University in Ada, Oklahoma. He completed his postdoctorate degree in genetics and developmental biology from UT Southwestern. He later completed a postdoctoral fellowship in orthopedic research and cell biology at Washington University School of Medicine in St. Louis. Dr. Karner joined the UT Southwestern faculty in 2020. At UT Southwestern, Dr. Karner is on the Propel Mentorship Program Mentoring Committee. Dr. Karner's lab at UT Southwestern focuses on deciphering the role and regulation of cellular metabolism during cell fate specification and differentiation in the context of bone development and disease. Dr. Karner is a member of the Society for Developmental Biology, the American Society for Bone and Mineral Research, the Orthopaedic Research Society, and Advances in Mineral Metabolism.
