The Hausdorff Center for Mathematics (HCM) at the University of Bonn brings together researchers in mathematics and its applications, including in particular quantitative economics. In these areas of research, the center is looking to appoint up to four W2 Professorships (Bonn Junior Fellows) These are temporary appointments for a period of five years. Some positions may be endowed with tenure-track, and, in exceptional cases, a position may be tenured immediately. The professorships The professorships intend to encourage independent research by outstanding early career researchers, analogously to the research groups of the Max Planck Society or the Emmy Noether Program of the German Research Foundation (DFG). The professorships are endowed with travel and guest funds during the initial period. Bonn Junior Fellows also have access to additional resources of the Hausdorff Center. Bonn Junior Fellows are encouraged to supervise doctoral students. The candidates We are looking for early career researchers holding a doctoral degree who are starting to develop their own research agenda. Suitable candidates should have already demonstrated scientific independence with relevant publications. Candidates should have some international research experience. They will contribute to our advanced teaching program. German language skills are not required. Research focus We seek candidates who fit into the broad spectrum of the Cluster of Excellence and complement the existing expertise. Depending on the candidate's research focus, candidates become members of the "Faculty of Mathematics and Natural Sciences" or of the "Faculty of Law and Economics" at the University of Bonn. The general conditions of employment are according to § 36 of the Higher Education Act of North Rhine-Westphalia (Hochschulgesetz des Landes Nordrhein-Westfalen). The University of Bonn is committed to diversity and equal opportunity. It is certified as a family-friendly university.
