Contact: 66011096

Dr. Titze serves as Associate Professor at the Cardiovascular and Metabolic Disease Programme of Duke-NUS Medical School. He also holds appointments as a Professor for Electrolyte and Circulation Research at the Friedrich-Alexander-University of Erlangen-Nuremberg in Germany, and at the Division of Nephrology at Duke University, USA. He is an elected member of the American Society of Clinical Investigation and the European Academy of Sciences and Arts.

His research focuses on how the body organizes osmolyte metabolism to maintain body fluid homeostasis. His interdisciplinary clinician-scientist team conducts basic and clinical studies to understand how kidney, skin, liver and skeletal muscle coordinate their organ functions to achieve constant body fluid homeostasis.

Questioning traditional physiological concepts, we have begun to rethink therapeutic strategies against diabetes and hypertension. We also provide with new mechanistic insights into how the immune system protects against infection and tumors, and offer alternative views on the pathogenesis of autoimmune disease.
Our research teams work collaboratively in the clinical research and molecular physiology research domain. The molecular physiology projects headed by our junior research associates focus on how the kidney, the liver, skeletal muscle, the skin, and the immune system residing in the lymphatics interconnect into a physiological network that regulates salt and water homeostasis. The patient-oriented projects headed by our junior clinician research associates transfer these findings into clinical practice, relying on deep clinical phenotyping with innovative methods such as 23NaMRI imaging studies for non-invasive detection and quantification of otherwise hidden sodium stores in humans. This interdisciplinary science approach has resulted in new research avenues for current understanding of the underlying cause of diseases of the aging organism, such as arterial hypertension, diabetes mellitus, autoimmune disease and host defence, and muscle and bone loss.
