Some Recent Additions to the Editorial Board

My research in environmental fluid mechanics involves turbulence and mixing in natural flows, such as rivers, lakes, and the ocean. In particular, I study turbulence and mixing in stratified flows, double diffusion, bubble plumes, and dispersion and contaminant transport in rivers. I have also applied this work in collaboration with aquatic ecologists to study the movement of zebra mussels, an aquatic invasive species, in rivers. Because my research has included laboratory experiments and field experiments, I am also interested in instrumentation, including acoustic methods of measuring velocity.

I received B.S. and M.S. degrees in civil engineering from the University of Illinois and a Ph.D. in mechanics and hydraulics from the University of Iowa at the Iowa Institute of Hydraulic Research. I am currently Professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology, where I teach a graduate course sequence in open channel hydraulics and sediment transport. In addition, I have taught continuing education courses on river hydraulics, culvert design, and bridge scour. My most recent experimental research centers around the sediment-water interface in natural watercourses and the hydrodynamic processes that occur there, such as flow resistance, cohesive sediment resuspension, and local bridge scour. I have written numerous research publications on thermal hydraulics, open channel flow resistance, compound channel hydraulics, bridge foundation scour, and resuspension of cohesive sediments, as well as a recent textbook on open channel hydraulics published by McGraw-Hill in their Water Resources and Environmental Engineering Series.

I am Senior Research Fellow and Vice President of the Korea Institute of Construction Technology (KICT) in Ilsan, Korea. After graduating from the Department of Civil Engineering, Seoul National University, Korea, with B.S. and M.S. degrees, I continued my studies in the Department of Civil Engineering, Colorado State University, where I earned my Ph.D. in December 1985. Before I joined KICT, I was Research Assistant Professor, Department of Civil and Environmental Engineering, University of Cincinnati, from May 1986 until September 1988. I am a Professional Engineer registered both in Korea and in the state of Ohio, and have been a member of ASCE since 1985. My interests and expertise lie in the field of sedimentation engineering, river mechanics, and ecohydraulics. I have published more than 100 technical papers and a few dozen research papers written either in English or Korean and a book, River Hydraulics (in Korean) for college students and practicing engineers in river engineering.
