Dr. Zechner is originally from Germany and completed his medical school and research doctorate at the University of Freiburg, combined with a research fellowship at Yale University. After a medical internship at the University of Würzburg, he completed a postdoctoral fellowship in the laboratory of Dr. Daniel P. Kelly at Washington University in St. Louis and the Sanford-Burnham Medical Research Institute at Lake Nona. Subsequently, he moved to UT Southwestern to complete his clinical training in internal medicine and endocrinology as a member of the Physician-Scientist Training Program. He joined the laboratory of Drs. David J. Mangelsdorf and Steven A. Kliewer to study intestinal hormones and their actions on energy and phosphate metabolism. In his spare time, Dr. Zechner enjoys biking in the Texas heat, playing and watching soccer, and taking advantage of the great cultural opportunities that Dallas offers, especially the symphony.
