Postdoc in Computer Science (University of Copenhagen)

We are seeking a highly motivated and experienced full-time Postdoc to join the research group of Jessica Hjaltelin for a 2-year position (with the possibility of extension) from October 1st, 2025, or soon thereafter. The successful candidate will work on a project leveraging multimodal health registry data and artificial intelligence (AI) to enable early prediction of ovarian cancer onset. Our research The Hjaltelin Group develops machine learning and AI models for 1) early detection of complex diseases, 2) prognostic prediction of patient outcomes, and 3) explaining longitudinal symptoms and risk factors, with a focus on translating these insights into clinical practise. The group utilizes Danish longitudinal health registries and electronic patient records, comprising hospital diagnoses, primary care events, laboratory measurements, medications, and clinical images. Additionally, we integrate these multimodal data to molecular systems-level data such as protein levels and genomics. The group is highly collaborative within-department, with international research teams, and clinical experts to help translate results into clinical practice. Place of employment The Hjaltelin group is part of the Section for Health Data Science & AI (HDSAI) at the Department of Public Health, located at the Panum Institute. Our research facilities include modern offices and workspaces, and we offer a dynamic and creative research environment with many opportunities. The group conducts cutting-edge research using large multimodal health data, deep learning, and translational science. The section has a collaborative spirit and is interdisciplinary, covering bioinformatics, statistics, machine learning/AI, and computer science. Project description The postdoc will apply machine learning/deep learning approaches along with explainable AI methods for early prediction and understanding of ovarian cancer onset. The postdoc will investigate and stratify trajectories leading to ovarian cancer. The aim is to discover novel risk factors and early symptoms that can help identify high-risk patients early on to pioneer a new era for cancer prediction and screening. The postdoc will lead the project while receiving continuous support from the PI and fellow group/section members.
