The project sits in the gastrointestinal epidemiology group and focuses on understanding and preventing liver disease, especially alpha-1-antitrypsin deficiency , with potential work on PSC and MASLD . The research environment combines epidemiologists, clinicians, and database administrators in a highly collaborative and international setting. The position draws on Sweden’s nationwide health registers and the unique ESPRESSO cohort, a large histopathology-based database of biopsy reports and linked healthcare information.

Experience in register-based research and gastroenterology/hepatology is considered a merit, as is the ability to supervise PhD students and work both independently and in teams. The appointment is for 2 years , with a possible extension after evaluation. The application deadline is 2026-08-03 . Applicants must submit a CV, PhD certificate, personal letter, publication list, and summary of current work, and also complete a statistical task using materials provided through the linked GitHub repository.
