I am a clinically-trained epidemiologist currently focusing on electronic health records research on non-communicable disease, including skin and inflammatory conditions.

I completed a PhD and MSc Epidemiology at the London School of Hygiene & Tropical Medicine, and a Medical Degree at the Medical University of Vienna.

I organise the short course "Introduction to Pharmacoepidemiology" (Part of the "Certificate in Pharmacoepidemiology") and teach on several other courses, including the "Analysis of Electronic Health Records", "Data Challenge", and Epidemiology-related MSc modules. I supervise summer projects for the MSc Epidemiology and MSc Health Data Science.
