Chris Marx starts as an Associate Professor in Biological Sciences in January of 2014. Following double majoring in Biology and Environmental Engineering at MIT and doing undergraduate research with Penny Chisholm, he earned his doctorate in Microbiology at the University of Washington with Mary Lidstrom. His thesis work explored the physiological challenges of the unusual methanol-utilizing metabolism of Methylobacterium. After becoming interested in evolutionary questions, he chose to pursue his NSF Microbial Biology Postdoctoral Fellowship at Michigan State University with Rich Lenski. Chris started his own group at Harvard University in 2005 in the Department of Organismic and Evolutionary Biology. Although the systems are varied, the major theme of the lab's work has been to forge connections between underlying physiology and evolutionary and ecological outcomes, using mathematical models to generate quantitative, testable predictions.
