Circadian behavior is much richer than wheel running. Animals sleep, explore, feed, groom, rear, interact, and engage in many other behaviors that each have their own temporal organization.

We developed the Circadian Behavioral Analysis Suite (CBAS) to identify and quantify multiple home-cage behaviors continuously across days. This allows us to study not only whether individual behaviors are rhythmic, but also how their phases are organized relative to one another.

Using this approach, we investigate how behavioral timing is shaped by factors including sex, estrogen, and molecular clocks in downstream neural circuits. The broader goal is to understand the circadian organization of behavior as a coordinated system rather than as a collection of isolated rhythms.
