I currently hold an MRC Skills Development Fellowship entitled "BMI trajectories in middle to old age: methodological developments, missing data and cost-effectiveness". The aim of the project is to develop methods for assessing BMI trajectories while accounting for missing data as individuals get older. The project has three components: (1) latent growth modelling of BMI trajectories using observational data; (2) longitudinal missing data methods development; (3) adaptation of an existing diabetes prevention health economic decision model so that a range of current interventions can be evaluated for their economic and equity impact. During the fellowship I will be working across departments in the University, HEDS, Public Health and the Sheffield Methods Institute (SMI) as well as spending time at Division of Population Health, Health Services Research & Primary Care at the University of Manchester.
I became a member of staff in HEDS in September 2014 as a Research Associate in Health Econometrics and was promoted to Research Fellow in January 2020. Prior to working in ScHARR, I was funded by an ESRC CASE studentship in partnership with NICE as a PhD candidate, also in HEDS, supervised by Dr Mónica Hernández. My thesis was titled “A Public Health Approach to Childhood Obesity: The Role of Econometrics”. The thesis uses a variety of advanced econometric techniques over three empirical studies. These studies investigate the effects of breastfeeding on childhood obesity, the impact of family lifestyle on childhood obesity and the relationships between childhood obesity, family lifestyle and health.
Before joining HEDS, I completed an MSc in Financial Economics (2009-2010) in the Department of Economics and a BSc in Economics and Statistics (2006-2009) in the School of Mathematics and Statistics, both at the University of Sheffield.
