Wozniak is responsible for direction of the Food Safety Program under the National Research Initiative and serves as the National Program Leader for Food Biotechnology and Microbiology. He has broad experience in the regulation and registration of microbial biopesticides, such as fungal pathogens of insects, and plant-incorporated protectants (PIPs), such as maize and cotton engineered for insect resistance.
He has worked for the Environmental Protection Agency (EPA) and the USDA's Agricultural Research Service (ARS), conducting research on plant transformation techniques and biological control mechanisms for insects in sugarbeet.
After receiving bachelor's and master's degrees in biology from Drake University, Wozniak completed his PhD at the University of Nebraska-Lincoln, focusing his research on cell differentiation and protein synthesis in plants. He has also worked as a postdoctoral research associate on the development of insect-resistant cotton and tissue-culture manipulation of sugarbeet. Other pursuits include gardening, mushroom hunting, and finding the best cup of coffee in Central America.
