Chris Dupont, Ph.D.
Assistant Professor

Research Interests and Accomplishments

Dr. Chris Dupont is an Assistant Professor in the Microbial and Environmental Genomics department at JCVI. His primary research focus is microbial physiology and the environmental and evolutionary influence on physiological variation. For example, how do modern day gradients in environmental parameters (e.g. light, nitrogen, Fe availability) influence the genomic contents and cellular regulation in marine microbes? How have dramatic shifts in the global redox state over the past 4 billion years constrained the evolution of biochemical pathways and biogeochemical cycles? An integrated approach of wet-lab organismal work, field studies, and bioinformatics analyses is used to address these questions.

Prior to joining JCVI, Chris received his Ph.D. in Oceanography from the Scripps Institution of Oceanography where he studied a variety of subjects including oceanic nickel biogeochemistry and the evolution of Ni-superoxide dismutase.  Dr. Dupont received a Bachelor's in Natural Resources and a Master's of Biological and Environmental Engineering from Cornell University.
