Research in the Physics of Behavior Group
Research in the Physics of Behavior group (Group Leader: Tom Shimizu) focuses on developing a physical understanding of biological behavior. We develop in vivo experiments to measure dynamics at multiple spatial and organizational scales, as well as theoretical modeling and data analysis frameworks to connect phenomena across those scales. Primary model organisms are the bacterium E. coli, the nematode C. elegans, and the arbuscular mycorrhizal fungi (AMF), with occasional forays into the lives of other creatures.
