Dr. Towler obtained his medical degree and Ph.D. in biochemistry from Washington University, St. Louis, where his thesis work focused upon protein modification by covalent fatty acid acylation (N-myristoylation). He completed his medical residency and endocrine/metabolism fellowship at Barnes-Jewish Hospital in St. Louis, and is a board-certified internist and endocrinologist.
Dr. Towler brings to UTSW expertise in the endocrine physiology of bone and vascular disease that synergizes with our Institution’s strengths in patient-oriented, bench-to-bedside translational research. Before joining UT Southwestern, Towler was the Lang Professor of Medicine in the Division of Endocrinology, Metabolism, and Lipid Research at Washington University and also served as Chief, Division of Bone and Mineral Diseases for a decade.
In addition to his career in academic medicine, Towler spent four years in the pharmaceutical industry, and is co-inventor of novel, patented selective androgen receptor modulators (SARMs) with potential clinical applications in treatment of musculoskeletal frailty. His clinical interests emphasize the diagnosis and treatment of bone and mineral disorders.
Dr. Towler is currently the Principal Investigator for projects supported by the National Institutes of Health (NIH), the American Diabetes Association, and the Burroughs Wellcome Fund. His research focuses upon Wnt signaling in arterial calcification (hardening of the arteries) and associated protein arginine methylation/deimination regulatory relays as potential therapeutic targets in aortic and peripheral artery disease. Dr. Towler’s research has been recognized by the Charles E. Culpeper Foundation (1996), the American Society for Bone and Mineral Research (Fuller Albright Award 2000), and the American Society for Clinical Investigation (elected in 2004). He currently serves on the editorial board of Arteriosclerosis Thrombosis and Vascular Biology. A former regular member of the NIH Skeletal Biology Development and Disease (2004-2008) and Atherosclerosis and Inflammation of the Cardiovascular System Study Sections (2010-2014), he also served as a member of the External Advisory Panel to the Illuminating the Druggable Genome Consortium for the NIH Center for Advancing Translational Sciences (NCATS; 2014- 2016).
Dr. Towler’s interests outside of biomedicine include his family, kayaking, and fly fishing.
