Michael Elowitz is a molecular biologist who is laying the groundwork for the next stage in the genomics revolution — understanding how genes interact. To do so, Elowitz employs a strategy of designing artificial genetic “circuits,” first modeling them computationally and then introducing the elements in vivo to test their activity. Michael Elowitz received a B.A. (1992) from the University of California, Berkeley, and a Ph.D. (1999) from Princeton University. Since 2003, he has served as an assistant professor of biology and as an applied physics Bren Scholar at the California Institute of Technology. His numerous articles have appeared in such journals as Science, Nature, and Proceedings of the National Academy of Sciences USA..
