Bradley Dixon, MD

Research Interests

My research interests are primarily focused on diseases of the kidney caused by abnormalities in the complement system, specifically atypical hemolytic uremic syndrome (aHUS), C3 Glomerulopathy (C3G), and Membranoproliferative Glomerulonephritis (MPGN). These interests are focused on development and improvement of blood tests that are used to diagnose these diseases, as well as clinical trials in new medications being developed to treat these diseases. I also have a clinical research interest in the wide variety of kidney diseases that have a genetic cause, especially cystic kidney diseases but also tubular diseases like Bartter syndrome and Gitelman syndrome, and glomerular diseases like Alport syndrome.
