Biography

After I finished my Ph.D. degree at OSU, I joined as a chemistry faculty in Keimyung University, Korea. I spent one year in developing fire retardents useful to polyester fabrics collaborating with fiber chemists (1991-1992). I spent the next several years, partly in developing fluorosensor using fiber optic system and partly in Tensor LEED calculation and mainly working on hydrodeoxygenation catalysis including preparation, characterization and investigation of the proper mechanisms via TPD and FTIR technique by the support of Korean Academic Science Foundation (1994-1996). Then, I had roled as one of the initializing committee member for Regional Research Center designated by Korea Ministry of Science and Technology and Korea Science and Engineering Foundation. Here, I spent three years mainly in developing catalyst materials aimed to be used in automotive catalytic converter, preparing and characterizing ceramic composites composed of alumina, zirconia and titania(1996-1998, KOSEF). I then spent one year in developing purification methodology of etching byproduct produced in the process of surface treatment of aluminum (1998-1999, supported by Namsun Aluminum Corp.). I also carried out research project of developing functionalized rubber material with the property of fire resistance supported by rubber company. After that, I performed analyzing and reducing project of VOC emitting from electronic/chemical parts of PC/monitor (1999-2000, Samsung Electronics) and developing gas burner for industrial dryer (2000-2001,Woosuck Eng.,) The next research projects that I had worked for 6 years (2003-2008) include studies of developing gas sensors based on metal oxide semiconductor materials detecting various VOCs and toxic gases emitted from industrial fields and amine-series gases produced from rotten meat and fishes.
