Introduction
I am currently Associate Professor (Ph.D. in Nutrition) at Tehran University of Medical Sciences (TUMS). We apply several methodological approaches, including clinical trials, epidemiology, and literature reviews to generate, translate and apply new knowledge to prevent chronic disease and mortality. We conduct pairwise and dose-response meta-analyses to pool and synthesize findings from studies and to assess the strength of evidence.
