Professor Kuehn completed a Ph.D. in Chemical Physics at Cornell University studying on non-contact friction and magnetic resonance force microscopy. During his postdoctoral research Dr. Kuehn began work in biology at The Rockefeller University. There he pursued measurements of population dynamics in microbial communities and behavioral diversity in microbes.

Research Statement

The Kuehn lab makes quantitative measurements of ecological and evolutionary dynamics. Our research is directed towards understanding the fundamental principles governing dynamics in complex biological systems at two levels of organization. First, we use model microbial systems to study stability and adaptation in microbial communities. Our second line of inquiry uses bacterial motility as a model system to ask fundamental questions about the role of phenotypic variation in evolution and the structure of the genotype-phenotype map.
