Biography

My research is focused on understanding the mechanisms and significance of biological (circadian) clocks, which regulate processes from gene expression to behavior. My projects integrate genetic, biochemical, and physiological experiments with current genomic approaches. Some recent work is listed below, and more can be found on my PubMed page. Please visit my website for more details.
