Overview

My overall focus is on the physiological control of circadian rhythms in animals. I have worked with several species of birds, mammals, and I currently work on marine invertebrates. In these studies I have investigated the role of neural and hormonal factors as well as the interaction of the circadian clock with various behavioral and physiological outputs. Locomotor activity is often used because it is a convienent output from the clock and it is easy to measure.
