Epidemiologist | Real-World Health Data (CPRD, EHR) | Study Design & Statistical Modelling

Profile Summary

I am a Research Fellow at the London School of Hygiene & Tropical Medicine (LSHTM) with extensive experience analysing large-scale healthcare datasets to generate robust, decision-ready evidence. My work focuses on epidemiology, real-world data, and advanced statistical modelling, supporting both academic and applied research. I specialise in all regression analyses, survival analysis, multistate models, and causal inference methods, with hands-on experience working with electronic health records (including CPRD) and large cohort datasets. I have led and contributed to studies examining complex health outcomes. I support organisations across the full research pipeline from study design and protocol development to data analysis, interpretation, and manuscript writing. My approach is rigorous, transparent, and tailored to deliver results that are suitable for publication, regulatory reporting, or strategic decision-making. I am happy to discuss your project and provide tailored support to help you achieve high-quality, impactful results.
