About me
Marie-Stéphanie Aschtgen, Assistant Professor at the Department of Microbiology, Tumor and Cell Biology (MTC) at Karolinska Institutet (Birgitta
Henriques-Normark Unit).My research focuses on the bacterial molecular mechanisms underlying host-bacteria interactions. I defended my PhD in Microbiology on bacterial Type VI secretion systems in the Prof Eric Cascales lab (Marseille, France). Then, I did a post-doc with Prof. Edward Ruby and Prof. Margaret McFall-Ngai (Univ. of Wisconsin-Madison, USA) studying host-symbiont interactions in the elegant model of the Euprymna scolopes-Vibrio fischeri symbiosis. I then joined Prof. Birgitta Henriques-Normark’s lab at the Karolinska Institutet for a second post-doc focusing on host-pathogens mechanisms of Streptococcus pneumoniae and Klebsiella pneumoniae and became Assistant Professor in 2019.
