Assistant Professor of Chemistry
Dr. Ki joined Stockton in 2016 after teaching and researching at the Rutgers University-New Brunswick. He completed his PhD degree at the Rutgers University-New Brunswick in the area of white light emitting phosphors. Dr. Ki pursued postdoctoral studies at the Purdue University and University of Washington to develop low-cost, efficient thin film solar cells. He had also industrial experience in silicon valley as a research scientist focusing on research and development of emerging solar cells.

My research focuses on studying the structure and properties of emerging earth abundant
semiconductor materials for energy related applications, such as phosphors for solid
state lighting, electrodes for water splitting, and absorbers for thin film solar
cells. We are also interested in developing multifunctional porous inorganic materials
by using molecular precursor routes to control electron and mass transport, electronic
and ionic conduction, electron-transfer kinetics to enhance device performance. Students
will have an opportunity to learn the design, synthesis, and characterization of new
semiconductor materials to understand their structural, physical, and chemical properties.
