Welcome

Theresa Fink has joined the lab for her Master thesis.

The Bischofs lab studies complex adaptive traits (CATs) of stressed bacteria. Our goals are to understand, to control and to engineer such traits. Using tools from molecular biology, microscopy and mathematical modelling we investigate how signaling networks regulate CATs. We seek to reveal fundamental organizing principles that relate the molecular network design to population-level behavior and vice versa. This should facilitate rational manipulations of bacterial populations and the implementation of novel functionalities into “smart” communities in the future.

The µCATs Lab is an independent Research Group of the MPI for Terrestrial Microbiology. We work in close collaboration with other groups from the BioQuant and the University of Heidelberg and also enjoy collaborating with external groups.
