Calvin Henard

Assistant Professor

Dr. Calvin A. Henard received a B.S. in Molecular Biology from Tarleton State University in Stephenville, Texas and a Ph.D. in Microbiology from the University of Colorado Anschutz Medical Campus in Aurora, Colorado where he studied the role of the nutrient starvation stringent response in Salmonella's ability to co-opt and subvert host immune responses. Following his doctoral studies, Dr. Henard was an NIH Ruth L. Kirschstein postdoctoral trainee at the University of Texas Medical Branch in Galveston, Texas where he evaluated virulence mechanisms of the intracellular protozoan parasite Leishmania. In 2014, Dr. Henard joined the National Renewable Energy Laboratory's National Bioenergy Center as a postdoctoral researcher, where he was promoted to a full-time staff researcher in the applied biology group in 2016. At NREL, Dr. Henard used his expertise in molecular microbiology and metabolic engineering to develop algal, yeast, and bacterial biocatalysts for conversion of renewable substrates to biofuels and bioproducts. In 2019, Dr. Henard joined the Department of Biological Sciences and the BioDiscovery Institute at the University of North Texas (UNT). Dr. Henard's lab at UNT leverages advanced molecular and synthetic biology to develop biotechnologies for the conversion of C1 substrates to fuels and chemicals using methanotrophic bacteria.
