Research Interests

Dr. Mullen's research interests are in creating complex surface structures with molecular-scale organization and chemical functionality for applications ranging from bioactive surfaces to nanoelectronics. His research centers on improving and enhancing unconventional lithographic strategies (such as scanning probe lithography, contact printing, particle lithography, etc.) using molecular self-assembly. Such hybrid strategies are of particular interest because they couple a key aspect afforded unconventional lithography, the ability to create complex architectures over large areas without the requirement of expensive facilities, to the flexibility and resolution afforded by molecular self-assembly. The goal of Dr. Mullen’s research program is to fabricate complex mesoscale surface architectures economically for the electronic industry and to extend these strategies into fields outside of traditional semiconductor fabrication. Given the interdisciplinary nature of his research program, undergraduate research students collaborate with faculty in various departments across the UNF campus and receive broad scientific training in preparation for their careers beyond the University of North Florida.
