Education

PhD, Materials Science & Engineering, Seoul National University, Korea, 2000.

Professional Interests

Dr. Lee’s current research interests include energy and/or electro-optical applications of nanostructured materials. Specific emphasis is place on 1) photovoltaic application of wide band-gap nanoparticles, 2) material processing of electronic materials in forms of nanoparticles, bulk ceramics/crystals, and thin films, 3) optical and magnetic properties of nanoparticles, and 4) the surface modification using ion implantation and chemical methods.  Before joining the University of Pittsburgh, he also carried out the research on domain/strain engineering of ferroic materials and composite design of biomaterials.

curriculum vitae

Jung-Kun Lee joined University of Pittsburgh in September 2007 as an assistant professor after more than 5 year service at Los Alamos National Laboratory.  He received his Ph. D degree from the Department of Materials Science and Engineering at Seoul National University, Korea.  His thesis was on superior electronic properties of domain engineered ferroelectronic thin films and crystals.  Then, he won highly competitive Director’s Postdoctoral Fellowship of Los Alamos National Laboratory and joined Los Alamos in January, 2002.  In Los Alamos, he has been involved in several research projects on photovoltaics, nanoscience, spintronics, and semiconductors. Due to his strong performance as a Postdoctoral Fellow, he was promoted to a technical staff member in January, 2005.  His major research topics include sophisticated processing and characterization of nanostructured materials and electronic materials for photovoltaic and information technology.  The scientific quality of his research is validated by more than 80 publications in refereed journals.  He also holds 10 patents on the dielectric and optical applications of functional materials.
