Open Doctoral Position at Krüger Lab

Expression of the multi-functional protein TIMP-1, which can act as a protease-inhibitor as well as a cytokine, positively correlates with progression of virtually all immune-associated diseases, including inflammation and cancer. At Krüger Lab they have discovered that TIMP-1 expression determines sex-disparities in liver metastasis and survival in pancreatic cancer (Hermann et al. J Exp Med 218:e20210911, 2021). Within this project they plan to investigates the cause of sex-specific TIMP-1 gene expression using suitable genetically modifies cell culture systems, mouse models combined with a broad spectrum of molecular-biochemical as well as in silico methods, also in cooperation with different partner labs.

If you have an M.Sc. in biochemistry, biology, molecular biotechnology or similar, and would like to work towards a PhD or Dr. rer. nat., please contact Prof. Krüger here.

Krüger Lab employs a wide spectrum of technologies encompassing all aspects of molecular cloning/genetic engineering, expression-vector design, biochemistry, cell culture including functional cell-assays, metabolic assays, protein-design and purification, flow-cytometry, histology, in silico-modeling, TIMSTOF, statistical analyses, bioinformatics etc. in order to explore the biology of TIMP-1.
Through cooperation with colleagues in the clinic they constantly validate their data with material from the clinic towards a transfer of new knowledge from bench to the bedside.
