James, originally from Fort Lauderdale Florida, received his B.S. degree in chemistry from the University of North Florida in Jacksonville. During his time there he conducted research under Dr. Kenneth Laali in the field of ionic liquids. James received his Ph.D. from the Georgia Institute of Technology in 2017 under the advisement of Dr. John R. Reynolds. During his graduate research he studied synthesis and characterization of conjugated polymers for various applications, including energy storage, thermopower, plasmonic resonance tuning of nanoparticles, and electrochromism.
