CV Caroline Barisch

 

Caroline Barisch studied biology at the University of Bayreuth and received her PhD from the University of Kassel in 2010. During her PhD in the lab of Prof. Markus Maniak she isolated lipid droplets from the model organism Dictyostelium discoideum and characterized the lipid droplet proteome.

In 2011, Caroline Barisch started her postdoc in the lab of Prof. Thierry Soldati at the University of Geneva, Switzerland. During the first years, she used the D. discoideum / M. marinum infection system to study lipid droplet dynamics during mycobacteria infection. 2016 she was promoted “maître assistante” and established several tools to monitor lipid flows from D. discoideum to intracellular mycobacteria. Besides lipid metabolism, Caroline Barisch also worked on zinc and ZnT transporters and their role in the bactericidal defense of D. discoideum and during mycobacteria infection.

In September 2019, Caroline Barisch started the junior research group Molecular Infection Biology at the University of Osnabrück, Germany. The main research interest of the group is to unravel the molecular mechanisms by which intracellular mycobacteria acquire host lipids. To this end, the lab is setting up metabolic tracing tools and mass spectrometry lipidomics. With the help of fluorescent and bifunctional lipid probes, her group will monitor the consequences of blocking specific lipid supply routes on various stages of the mycobacterial infection course.
