Dr. Karner is originally from Oklahoma. He earned his Ph.D. at UT Southwestern in the laboratory of Dr. Thomas Carroll where he studied WNT signaling in the developing kidney. After this, he received postdoctoral training at Washington University School of Medicine in St Louis, Missouri where he studied the interplay of WNT signaling and cellular metabolism during osteoblast differentiation. He next established his laboratory in the Department of Orthopaedic Surgery at Duke University in Durham, North Carolina. While at Duke, Dr. Karner identified glutamine as a critical nutrient regulating multiple stages of osteoblast differentiation. Dr. Karner is excited to bring his expertise in developmental bone biology, WNT signaling and amino acid metabolism back to UTSW. His laboratory focuses on the role and regulation of amino acid metabolism during cell fate specification and differentiation with a special emphasis on identifying novel bone forming therapies. Outside of the lab, he has limited personal interests outside of cooking and chauffeuring his children to various sporting or school related events.
