IntroductionThe 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 Beate Kümmerer lab (arboviruses) at the Institute of Virology, in collaboration with the Florian I. Schmidt lab (nanobodies and innate immunity) at the Institute of Innate Immunity, both at the University Hospital Bonn (Germany), is looking for a highly motivated





PhD student (m/f/d)




for an exciting project focusing on nanobodies against orthoflaviviruses to be filled at the earliest possible date. The 3-year part-time position (65%) is within the framework of the TTU Emerging Infections program of the German Center for Infection Research (DZIF).

The aim of the project is to generate nanobodies as a potential therapeutic against orthoflaviviruses, preferentially against viruses circulating in Germany like e.g. WNV but also against other orthoflaviviruses causing epidemics worldwide. To be able to also target orthoflaviviral induced encephalitis, we particularly aim to deliver nanobodies to the brain comparing several strategies. The functionality of the nanobodies shall be evaluated in neutralization assays and blood brain barrier models such as transwell assays.
