Your future with us

We are looking for an enthusiastic PhD student to join our Integrated Cancer Research Laboratory at the CECAD Research Center in Cologne. The position is part of a newly funded project that aims to build and design digital twins for patients with cancer. The project builds on one of the largest and most comprehensively annotated longitudinal CLL research platforms worldwide, comprising well over 10,000 patients from prospective trials and registries of the German CLL Study Group (GCLLSG), with detailed clinical, genomic, transcriptomic and measurable residual disease (MRD) data. As a PhD student, you will help build a multimodal AI foundation model that integrates longitudinal clinical, genomic, transcriptomic and MRD data to construct “digital twins” of individual patients with CLL. Using self-supervised deep learning and representation learning techniques, you will develop models capable of forecasting disease trajectories, including relapse, treatment response, Richter transformation and second primary malignancies, and of simulating outcomes under different therapeutic scenarios. Through this work, you will contribute to a new generation of AI-driven, personalized risk prediction tools and help translate computational insight into improved care for patients with CLL.

We are one of the leading university hospitals in Germany and network research, teaching and health care at the highest level. Thats why many things are a lot bigger for us: the spectrum of exciting development opportunities. The limitless openness with which specialists from all over the world work together here. Or our commitment as an employer to support all employees as best we can in reconciling their job with their goals and life situations.

This is the University Hospital of Cologne: Everything but ordinary.

Your future in detail

The Integrated Cancer Research Laboratory ( led by Prof Othman Al-Sawaf and based at the CECAD and Department I of Internal Medicine, was founded in 2024 and is funded by a large EmmyNoether-Grant of the German Research Council (DFG). The focus of the lab is to integrate multimodal analyses to study the plasticity, evolution and prognosis of cancer with a special focus on hematological malignancies. To this end, the lab utilizes a unique biobank with blood and bone marrow samples from patients treated within large (900
