Michael Rosbash

Michael Rosbash is Professor of Biology at Brandeis University and Investigator of the Howard Hughes Medical Institute. Rosbash uses genetics to understand the underlying mechanisms of circadian rhythms. In 1984, Rosbash, along with collaborator Jeff Hall, cloned the period gene in Drosophila, which led them to discover the transcriptional negative feedback loop of circadian clocks…
