Per Hall

Per Hall is a Professor in the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet, with a part-time clinical position at Södersjukhuset. His primary focus is breast cancer prevention and early detection, combining clinical practice with research. He leads the Karma Project, a large-scale cohort study enhancing risk prediction through mammographic features and genetic markers. His work includes developing risk models for personalized screening and evaluating interventions like tamoxifen to reduce breast cancer incidence.

Research interests include mammographic density, polygenic risk scoring, and clinical trials assessing drug efficacy (e.g., tamoxifen metabolism). Key projects include SMART (stratified screening trial) and KARISMA (tamoxifen trials). Awards include the 2021 Breast Cancer Association Award for contributions to prevention and early detection.

Grants include EU Commission projects, NIH funding, and major Cancer Society grants. Supervised over 20 students, many focusing on breast cancer epidemiology and risk assessment. Collaborates internationally on AI-driven risk models and biomarker research. Active in public outreach through initiatives like Karma Project resources for participants.
