Lehigh University - CEE: Tae Sup Yun

Assistant Professor of Geosystems Engineering

Department of Civil and Environmental Engineering
Lehigh University
13 East Packer Avenue
Bethlehem, PA 18015

Education

Ph.D. Civil and Environmental Engineering, Georgia Institute of Technology, 2005.
M.S. Civil and Environmental Engineering, Georgia Institute of Technology, 2003.
B.S. Geology, Yonsei University, South Korea, 1997.

Research Area and Interest

Central theme: energy and environment
Phenomena under consideration: coupled behavior of gas hydrate bearing sediments, fluid-mineral interaction, conduction and diffusion, nucleation and crystallization, physical behavior of treated geomaterials
Applications: viable methane production from gas hydrate, carbon sequestration, contaminant flow in porous media, innovative sensing methods, heat transfer, smart and sustainable geomaterials
Methodology: wave-based process monitoring, innovative experimentation at particle-level, signal processing and inversion problem solving, tomographic techniques.

Teaching

Dr. Yun taught courses in Soil mechanics and Foundation Engineering at Georgia Institute of Technology and Southern Polytechnic State University prior to join Lehigh University in 2007. He develops and teaches Geoenvironmental Engineering and a couple of graduate courses within his expertise at Lehigh University.
