Jonas Baumann studied biology at the Goethe-University in Frankfurt from 2001 to 2008. In his diploma thesis, he specialized in the field of aquatic ecotoxicology with a focus on "Ecotoxicity of nanoparticles in invertebrates". From 2009 to 2014, he deepened his research in this field during his PhD at the University of Bremen. From 2015 to 2021 he worked as study director and laboratory manager for ecotoxicological studies at the CRO Eurofins Agroscience Services Ecotox GmbH near Pforzheim. There he was also responsible for the scientific as well as technical supervision of the fish husbandry.

Since January 2022, Jonas is working as a postdoc and laboratory manager of the Zebrafish facility at the HIPS in the Department of Microbial Natural Products. As part of his work, he is entrusted with the organization of the fish breeding and the associated animal welfare tasks. He is also responsible for supervising the animal care staff as well as the fish culturing facility. He is particularly interested in the use of zebrafish embryos as an alternative in vivo vertebrate test model in terms of the 3R principle (Replacement, Reduction, Refinement). Jonas participates in the research on the toxicity of new compounds and the development of new infection models on fish embryos and supports the scientists at the HIPS in their research. In addition, he is responsible for the Zeiss Celldiscoverer 7 (Live Cell Fluorescens Imaging System).
