Dr. Bradley Johnston (PhD) is an Associate Professor with the Department of Nutrition. Prior to arriving in Texas, he trained in Kinesiology (University of New Brunswick), Experimental Medicine (University of Alberta), Evidence-Based Health Care (Oxford University) and Clinical Epidemiology and Biostatistics (McMaster University). Dr. Johnston subsequently held faculty positions at the Hospital for Sick Children Research Institute (2011 to 2017), the Dalla Lana School of Public Health at the University of Toronto (2011 to 2017), and the Department of Community Health and Epidemiology at Dalhousie University (2017 to 2019). His work involves the application of randomized trial, systematic review, meta-analysis and guideline recommendation methods to a wide range of areas, with particular interests dietary guideline methodology, and in teaching the principles and practice of critical appraisal and evidence-based nutrition.  As the director and co-founder of NutriRECS (www.nutrirecs.com), he leads an international consortium of researchers and research trainees aiming to develop high quality, value-added nutritional guideline recommendations on major nutrition, food and dietary pattern questions.
