Dr Haroon Ahmed
Senior Clinical Lecturer in Epidemiology. Director, Academic Fellows Scheme
Overview
I am a Clinical Reader in Epidemiology and Director of the Academic Fellows Scheme at the Division of Population Medicine, Cardiff University School of Medicine, and a practising GP at Rumney Primary Care Centre, Cardiff.
My research focuses on the prevention, diagnosis, treatment, and wider impacts of common infections. I am particularly interested in how infection and antibiotic treatment affects people with specific long-term conditions (e.g., cardiovascular disease), or multimorbidity. Most of my research uses causal inference methods and large-scale routinely collected health data, but I also have experience of large multi-centre clinical trials.
I have held back-to-back Fellowships from the NIHR [Doctoral, 2014-2019 and Advanced 2020-2023].
I collaborate with colleagues from UKHSA and academic institutions across the UK.
I Co-lead the Infections work package for the Health and Care Research Wales funded Wales Centre for Primary and Emergency Care Research (PRIME Centre Wales).
I have considerable interest in supporting clinical academic trainees. I am the Director of the Academic Fellows Scheme, a Welsh Government funded scheme that recruits, supports and mentors newly qualified GPs for two years and provides opportunities for research, teaching, and postgraduate study. I also co-Lead the Cardiff cohort of the WCAT programme and mentor GP Academic Trainees.
My teaching roles include Case-based learning modules, co-leading the infections module of the Population Health Intercalated BSc, and supervising MPH, SSC, and intercalated BSc projects.
