Rodney Dewayne Priestley (born 1979) is an American chemical engineer and professor at Princeton University. His research considers the phase transitions of polymers and their application in electronic devices and healthcare. In 2020 he was made the Princeton University Vice Dean of Innovation. He was named dean of The Graduate School effective June 1, 2022.

Early life and education

edit

Priestley grew up watching documentaries on National Geographic.[1] He originally considered studying marine biology or geology.[1] During high school he became increasingly interested in chemistry.[2] Priestley eventually studied chemical engineering at Texas Tech University and graduated in 2003, where he competed in long jump.[3] As part of a Research Experiences for Undergraduates programme at the University of Connecticut Priestley first encountered polymers, in the context of a project to develop artificial bone materials.[1] He completed his doctoral degree at Northwestern University, where he studied nanoscale confinement of polymers. In particular, Priestley made use of fluorescence and dielectric spectroscopy to investigate how confinement and interfacial effects impacted the glass transition temperature and physical ageing of polymers.[4] Priestley was a postdoctoral fellow at the Ecole Superieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI).[5]

Research and career

edit

In 2009 Priestley returned to the United States and joined the faculty at Princeton University. At Princeton, Priestley studies the nanoscale properties of materials, and how to tune these for novel device applications.[2] He has continued to study the glass transition temperatures of polymers, with a focus on the controlled formation of thin films and nanocolloids.[6] Priestley has studied the transition temperatures of substances that are composed of two or more polymers, attaching fluorescent reporting tags to the different components and using the brightness of the tag to infer whether the polymer is in a glassy or rubbery phase.[7] As part of this work, Priestley studied plexiglas, a composite system of poly(methyl methacrylate) (PMMA) and poly(butyl methacrylate) (PBMA) that is found in coronary stents and paints.[7] He combines experimental studies with computational investigations to better understand the distribution of the PMMA and PBMA throughout the plexiglass.[7] Through his understanding of phase transitions, Priestley has shown that it is possible to precisely control nanostructures, and realised self-assembled biopolymers for use in artificial skin.[8] Alongside his work on polymeric systems, Priestley has investigated nanoparticles, specifically engineered nanoscale zerovalent iron (enZVI) particles, as a means to clean groundwater.[9] He proposed the use of Janus particles for the use in surfactant-free cleansing.[10]

In 2019 Priestley was promoted to full professor, and was one of the first African-Americans to hold such a position at Princeton University.[1] In 2020 he was made vice dean of innovation, and in 2022 named dean of The Graduate School.[11][12] He is the founder of the science-based Cativa health cannabidiol.[13] Priestley is an associate editor of JACS Au, an open-access journal.[14]
