TPS Fellow Parker Evans headshot

Parker received his BS in Plant Sciences and Microbiology from the University of Arizona (Tucson, AZ) in 2014. As an undergraduate Parker co-founded MycoCats, an organization which uses fungal biotechnology to recycle toxic waste products into substrates for sustainable food production. He completed an MS degree in the labs of Dr. Barry Pryor (Plant Pathology) and Dr. Don Gervasio (Chemical Engineering) working on biological fuel cells. His work coupled the biological and engineering aspects of enzymatic fuel cells with in situ catalyst regeneration. 

Parker specializes in interfacing electronics with living systems. His research in the TPSGP utilizes a novel device known as a programmable chemical actuator for the electronic control of biological processes. To this end he and his advisors have demonstrated fully reversible changes of pH and ion concentration using PCAs. Parker has used PCAs electronically control enzyme activity and natural rubber synthesis. Parker’s project will conclude with the development of programmable chemical actuators into a commercially available tool.
