Dr Tom Norris PhD
Senior Research Associate in Epidemiology and Biostatistics
Tom graduated from Loughborough University in 2011 with a 1st in Human Biology. He then continued at Loughborough to pursue a PhD in Human Biology and Epidemiology, completing in 2015. Between 2015 and mid-2016, Tom was employed as a Research Associate in Epidemiology at the University of Bristol. He then moved to the University of Leicester to take up a Research Associate post (Pregnancy and Perinatal Epidemiology). He returned to Loughborough University in May 2018 to work on an MRC- funded project entitled ‘Body Size trajectories and cardio-metabolic resilience to obesity in three United Kingdom birth cohorts’.
Tom works primarily with birth cohort and longitudinal studies, predominantly in the UK, but also in China and North America. One of Tom’s interests is the production of growth references and he has produced several birth weight references for British, South Asian and Chinese populations. Tom is also interested in methods to model longitudinal data, particularly multilevel models, to produce trajectories of, for example, fetal and infant anthropometry. Tom has then used these trajectories as either outcome in themselves or to serve as exposures to relate to distal outcomes. He also has interests in causal inference methods used with observational data.
