Dr. James Ritchie


Clinical Research Fellow – Center for Epidemiology, Institute of Population Health.


Dr. Ritchie is a specialty trainee in nephrology who is undertaking research within the Center for Epidemiology under the supervision of Professor Philip Kalra and Dr. Smeeta Sinha. His main program of research aims to better describe the effects of clinical presentation and medical therapy on prognosis in atherosclerotic renovascular disease. In addition to this he has interests in how novel analytical methodologies may increase the value of large-scale observational datasets.
