Complex Adaptive Traits (CATs)

Complex Adaptive Traits (CATs)

Dr. Ilka Bischofs-Pfeifer

Research area

Bacteria have evolved sophisticated strategies to cope with stress and adapt to environmental change. Our group studies complex adaptive traits (CATs) in beneficial Bacilli at the behavioral and mechanistic level. Our research reveals new traits and aims to understand how the gene regulatory network controls them. We specifically focus on spores and peptide-based signaling networks and seek to identify fundamental organizational principles relating the molecular network design to population-level behavior and vice versa. This should facilitate rational manipulations of bacterial populations and the development of probiotics in the future.
