I am a Professor at Department of Energy Resources Engineering at Pukyong National University, Korea. I am also leading the Geo-ICT Laboratory at Pukyong National University since 2011. Before that, I was a Post-Doc fellow at Department of Energy and Mineral Engineering at Pennsylvania State University, USA. In Penn State, I was one of the key members in Advanced Photovoltaics Research Group and also worked with R. Larry Grayson and A. Nieto (faculty in Mining Engineering Program). I visited Department of Geography at University of California, at Santa Barbara and worked with Keith C. Clarke for paper publications. I received a Ph.D under the supervision of Prof. Hyeong-Dong Park at Department of Energy Systems Engineering, Seoul National University, Korea in 2009. I received B.S. degree at School of Civil, Urban and Geosystem Engineering, Seoul National University, Korea in 2004.

I have been working in the area of Energy Resources Engineering, Mining Engineering, Geographic Information Systems (GIS), 3D Geomodeling, Operations Research, Engineering Geology, Solar Energy Engineering, Renewable Energy Systems and Energy Analysis.
