Rate My Professor Gibran Hemani

Professor Gibran Hemani holds the position of Professor in Statistical Genetics within the Bristol Medical School's Population Health Sciences division at the University of Bristol. He is a key member of the MRC Integrative Epidemiology Unit, serving as programme lead for Mendelian randomization. Hemani earned his PhD in quantitative genetics from the University of Edinburgh in 2012 at the Roslin Institute. After completing two years of postdoctoral research at the University of Queensland in Australia, he joined the University of Bristol in 2014, advancing through academic ranks to his current professorship. His career has focused on developing computational and statistical methods to harness large-scale genetic data for epidemiological insights.

Hemani's research centers on statistical genetics and causal inference, with particular emphasis on Mendelian randomization techniques to identify causal effects in complex traits and diseases. His interests encompass genetic influences on body-mass index and blood pressure, gene-environment interactions, the DNA methylome, polyunsaturated fatty acids and cardiovascular outcomes, and genetic risk factors for depression. Notable contributions include the development of the MR-Base platform for Mendelian randomization analyses and key methodological papers such as 'Gene-environment equivalence: The fundamental principle of Mendelian randomization' (PLOS Medicine, 2026), 'An evaluation of age-varying genetic effects underlying body-mass index and blood pressure in the UK Biobank' (PLOS Genetics, 2026), and 'Leveraging polygenic risk scores to infer causal directions in genotype-by-environment interactions between complex traits' (Human Genetics, 2026). He was awarded a Wellcome Trust Sir Henry Dale Fellowship in 2017 and has been named a Clarivate Highly Cited Researcher in 2024 and 2025. With over 52,000 citations, his work has profoundly influenced the field of genetic epidemiology.
