The University Hospital Bonn (UKB) is one of Germany’s leading university hospitals, combining top-level performance in medicine and research with excellence in teaching. Each year, more than half a million patients receive inpatient and outpatient care at the UKB. Around 3,500 students study medicine and dentistry here, and over 600 people are trained annually in healthcare professions. With approximately 9,900 employees, the UKB is the third-largest employer in the Bonn/Rhein-Sieg region. In the Focus hospital ranking, the UKB ranks first among university hospitals in North Rhine-Westphalia and second nationwide in terms of case mix index (case severity). In 2024, the UKB raised nearly €100 million in third-party funding for research, development, and teaching. The F.A.Z. Institute has named the UKB “Germany’s Training Champion” and “Germany’s Most Attractive Employer” for the fourth consecutive year.


The following part-time (25,025 hours/week) position is to be filled as soon as possible in the Institute of Clinical Chemistry and Clinical Pharmacology at the Faculty of Medicine of the Rheinische Friedrich Wilhelms-University Bonn:


PhD position (m/f/d) - Dietary regulation of immune cells

The position is available for an initial period of three years, with the possibility of extension.
We are seeking a highly motivated candidate to fill a Ph.D. student position in dietary immunology in the research group of Christoph Wilhelm at the University Hospital Bonn (UKB), University of Bonn. Dietary immunology is an emerging field that investigates how dietary compounds and metabolites regulate the immune system. The project will investigate how diets (e.g. high-fat diet, ketogenic diets) and dietary components drive or reverse inflammation and includes the analysis of metabolic pathways controlling tissue resident immune cells such as T cells and innate lymphoid cells (ILC) (Karagiannis et al. Nature 2022, Theodorou et al. BioRxiv 2024, Wientjens et al. Immunity 2025). To investigate these processes the candidate will use mouse models, transcriptomics, classical immunological methods but also cutting-edge technologies, such as imaging flow cytometry, metabolomics, proteomics and extracellular flux analysis. In addition, the project has potential to utilize links with clinicians to translate findings to human patients. The overall aim is to identify novel dietary intervention strategies that are effective to reverse inflammation in diabetes and to treat chronic inflammation. Candidates with experience in cellular immunology, molecular cell biology or biochemistry are specifically encouraged to apply.
