Chris Dupont is an Associate Professor in the Microbial and Environmental Genomics group at JCVI. His primary research focus is microbial physiology and the environmental and evolutionary influence on physiological variation. This involves work with model organisms in laboratory systems, domestication of wild microbes for model studies, and sequencing based profiling of microbial communities in a variety of environments, including organismal microbiomes.

Dr. Dupont is also working on applying synthetic biology and machine learning techniques to solve unique problems in big dataset associated with the human microbiome and the environment.

Dr. Dupont began his career at JCVI as a post-doctoral fellow. He received his Ph.D. in Oceanography from the Scripps Institution of Oceanography, as well as a Bachelor's in Natural Resources and a Master's of Biological and Environmental Engineering from Cornell University.
