Mason Clark is a PhD student in the interdisciplinary Ecology and Evolutionary Biology program at Texas A&M University. His research focuses on sterol metabolism in plant-feeding insects and physiological adaptations to cholesterol auxotrophy. He is conducting research to investigate genes required in plant sterol dealkylation as well as using CRISPR/Cas9 systems to modify sterol and terpenoid production in cotton. He received his B.S. in Environmental Biology from SUNY College of Environmental Science and Forestry, Syracuse, NY. Prior to joining Texas A&M, Mason worked in quantitative genetics and genome evolution, plant pathology, and vegetable entomology.
