Bradley Dixon, MD, joined the faculty in the Division of Nephrology and Hypertension at Cincinnati Children's in 2006. He has received support for his research from a William Cooper Procter Pediatric Research Award in 2006, a Child Health Research Career Development Award (K12) in 2009, and is currently funded by a K08 through the National Institute of Diabetes, Digestive and Kidney Diseases. Dr. Dixon’s research interests focus on the effects of hyperosmolal microenvironments such as the renal medulla and urinary bladder upon vital cellular processes such as the DNA damage response pathway and activation of cell cycle checkpoints and apoptosis. This research focus attempts to understand the susceptibility of the gastrointestinal tissues used in bladder reconstructions to carcinogenesis.
In addition to his basic science research interests, Dr. Dixon has a clinical research interest in thrombotic microangiopathies such as atypical hemolytic uremic syndrome (aHUS) and thrombotic thrombocytopenic purpura (TTP), and is an investigator in a number of clinical trials and registries for these diseases. Dr. Dixon is also involved in clinical research studying cystic kidney diseases such as autosomal dominant polycystic kidney disease (ADPKD).
