Dr. Heyns holds a doctoral degree in polymer science from Stellenbosch University, South Africa. Her doctoral thesis was on the development of the hydrophilic, biocompatible 3-methylene-2-pyrrolidone (3M2P) polymer class. The study included the design, synthesis and characterization, as well as the evaluation of the stimuli-responsive behavior of the 3M2P-based (co)polymers. The polymers were evaluated for their potential use in industrial applications (kinetic hydrate inhibitors for the oil and gas industry) and for biomedical applications (encapsulating biological material). Subsequently, she worked in the polyolefin processing sector in South Africa as a polymer scientist (2019-2020). Her expertise includes organic synthesis, reversible deactivation radical polymerization techniques and physical polymer chemistry of stimuli-responsive polymers. She joined The Kumar lab in July 2021, where her main research focus will be on designer polymer synthesis for drug delivery applications and beyond.
