CV

Jana Seifert studied Geoecology at the Technical University Bergakademie Freiberg, Germany. During her studies she got fascinated about microbiology and decided to move on this subject. She did her PhD in biology about the degradation of chloroaromatic hydrocarbons by gram-positive bacteria. As a Post-Doc she focused on geomicrobiology and analyzing microbial communities with molecular-genetic techniques. As a group leader at the Helmholtz Center for Environmental Research – UFZ in Leipzig, Germany she started to focus on the functionality of microbial communities setting up metaproteomics and protein-SIP. 2013 to 2018 she was a junior professor, since 2019 she is a full professor at the University of Hohenheim, Germany, where she works on the microbiome-animal interaction and the use of feeding resources by the gut microbiome.
