I specialise in research methodology, evaluation of statistical methods, and quantitative research on evaluation of effectiveness/safety of medications, devices, and interventions; how interventions and policies influence infectious diseases. My research has used a wide array of methods including (cluster) randomised control/clinical trials, quasi-randomosed studies, systematic reviews, cohort, case-control (test negative case control studies), and cross-sectional studies. 

I have use electronic medical records from several countries including USA, Europe (UK, Netherlands, Spain, Italy, Denmark) and secondary data from Brazil, Southern and Eastern Africa. I use simulation studies to evaluate statistical/data science methods in epidemiology.
