Robert Reenan, PhDEdit My Page
We are interested in evolution of brain function and behavior. Our primary model system is Drosophila, the fruit fly, for its powerful traditional and molecular genetics. Our main question ishow do genomes encode and regulate proteins involved in rapid electrical and chemical signaling in the brain, normally and in disease? Surprisingly, this has led us into studies of RNA editing, comparative genomics, small non-coding RNA, heterochromatin, evolution of RNA structure, and inherited neurological disorders.
Robert Reenan trained as a graduate student in the laboratory of Dr. Richard Kolodner at Harvard Medical School where he studied the process of DNA repair in yeast, discovering genes that would become important in human cancer. He then pursued post-doctoral work in the Laboratory of Genetics at University of Wisconsin-Madison under Dr. Barry Ganetzky. There, he started a lifelong love affair with behavioral neurogenetics studying, in particular, ion channel genes in the fruit fly. He began his independent career at the University of Connecticut Medical School in the Department of Genetics where he discovered the process of RNA editing in the nervous system of the fly. Reenan joined the faculty at Brown University in the summer of 2006.
