Biography

I am Canadian trained - medical school at Western University, London, Ontario, and Internal Medicine residency and fellowship in Gastroenterology at McMaster University, Hamilton Canada. I am dual board certifed by the RCPSC (Royal College of Physicians and Surgeons of Canada). I have been in community practice my entire career and did therapeutic ERCP for nearly 30 years. I have a masters degree in clinical epidemiology. I have research interests, mostly in upper GI disorders - like ulcer disease, reflux and H. pylori a bacteria in the stomach and how to treat this infection is a particular research interest. I am interested in clinical medicine and helping you, the patient, as much as possible, realizing that I cannot wave a wand and make any issue disappear. I have always been a patient advocate.

Professional Background

I am a Canadian trained physician, attending University of Western Ontario for medical school, then McMaster University, Hamilton, Ontario for Internal Medicine residency and Gastroenterology Fellowship. I did an extra clinical research year and also obtained further training in therapeutic ERCP. I was in private practice gastroenterology in Guelph, Ontario until 2019 and during that time was clinical faculty at McMaster University, becoming Clinical Professor in 2013. I worked for a 2 year stint in PEI, Canada before coming to URMC.

I have interest in evidence-based medicine with a MSc from McMaster University in clinical epidemiology and biostatistics. I have participated in numerous randomized, controlled trials. I have developed many professional guidelines and teaching programs for physicians. I am a fellow of the American Gastroenterological Association (AGAF 2011), the Canadian Association of Gastroenterology (CAGF 2015) and the American College of Gastroenterology (FACG 2022).

Research

My research interests started with Helicobacter pylori. I published the first meta-analysis (1992) on the treatment of Hp and treatment has been and remains my primary interest (Toronto consensus 2016). I have looked at the effects of Hp on dyspepsia and with the CADET (Canadian Adult Dyspepsia Empiric Treatment) study group, we performed a number of relevant, randomized controlled trials to get direct evidence to develop management guidelines for upper GI symptoms/disorders (CanDys guidelines). I am interested in the related areas of upper GI - GERD. I have contributed to national guidelines in GERD consensus conferences. I am an expert in PPI's, a mainstay of treatment of upper GI disorders. Teaching practising physicians has always been a keen interest. I also have background in evidence-based medicine with a masters degree from McMaster University, Hamilton, Canada.
