Dawit is an internationally experienced data scientist, epidemiologist, and public health specialist in big real-world data (RWD). He is a medical statistician and a health econometrician by training with professional accreditation (GradStat) from the Royal Statistical Society. Dawit commenced his research career at University of Birmingham (UK) while completing his PhD (2016-2019). Prior to that, his broad skill base was applied in his early professional career across a wide range of areas in the governmental and non-governmental (NGOs) sectors in the UK.

With background in both statistics and economics, Dawit’s research encompasses the intersection of biostatistics, epidemiology, and econometrics. He is interested in using real-world-data/electronic health records (EHRs) to investigate risk factors, trends, early diagnosis/prediction, and economic burden of chronic diseases as well as multimorbidity patterns to better understand disease clusters, their trajectories and underlying mechanisms.
