BIO:

 Dr. DeMichael Winfield is a Research Chemist with expertise in polymer and organic chemistry. He received his Ph.D. in Chemistry from the University of Georgia in 2021. His doctoral work focused on the synthesis and characterization of thermoplastics from plant biomass.  In 2022 Dr. Winfield worked as a Postdoctoral Research Associate in the Bio-oils research unit at NCAUR, where he developed sustainable synthetic methods for functionalizing oleochemicals for fuel and lubricant applications.

 Dr. Winfield joined the Bio-oils research group as a Research Chemist in 2023. His primary research focus is on the chemical modification of plant oils for industrial applications. Current projects include utilizing new crops as biobased feedstocks for applications as lubricants, biodiesel, polymers, and polymer additives. Another area of research is developing green, metal-free synthetic methods that are competitive with traditional industrial methods.
