James is a Ph.D. student in the Department of Electrical and Computer Engineering at the Pratt School of Engineering and also a research and development engineer in Duke’s Shared Materials Instrumentation Facility (SMiF) where he assists researchers in the use of characterization equipment such as MicroCT, SAXS, Micro-Strain Analyzer, XPS, SEM, XRD, EQE, Solar J-V and UV-Vis.

Current Research Focus

  • Understanding electrode interfaces of supercapacitor and photovoltaic devices via invacuuo deposition coupled with ultraviolet and x-ray photoelectron spectroscopy
  • Integration of a roll-to-roll processable organic photovoltaic and supercapacitor into a two-tiered flexible device
  • Optimizing a transparent pseudocapacitor electrode for a supercapacitor device composed of nickel hydroxide coated copper nanowires and studying its electrochromic behavior

Research Interests

  • Thin film photovoltaic materials
  • Supercapacitor electrode, separator and electrolyte materials
  • Understanding electronic structure of nanomaterials for energy applications
