III. RESEARCH AREA AND INTEREST

Main Research Directions: (1) energy and sustainable geotechnology, (2) biogeophysics and microbially engineered bio-soils, (3) physics and mechanics of porous and particulate materials, and (4) near-surface geophysical characterization and smart sensor application.

Methodology: theoretical/experimental studies of particle-level, pore-scale and macro-scale phenomena in particulate materials and porous media (mechanical, chemical, thermal, electrical, hydrological, and biological). Experimentation involves distinct laboratory devices and procedures, with emphasis on low-perturbation wave-based characterization and process monitoring (both elastic and electromagnetic waves), X-ray CT imageries (both micro- and core-scales), and related inverse problems.

Problems: resource recovery (petroleum, natural gas, EOR, methane hydrate, shale gas), geo-environment (geologic CO2 storage, soil remediation), and engineering systems (soil improvement, dynamic soil response, underground excavations).


IV. HONORS AND AWARDS

Visiting Fellowship at University of New South Wales, UNSW Canberra Appointed as the visiting fellow at UNSW Canberra from 30 June 2018 to 30 September 2018. The University made a contribution of AU$3,500 to support the living expenses during the visiting period. 

International Collaboration Fund by National Research Foundation of Korea (NRF). July 2018. KRW 6.2 million. 

ExCEEd 2012 Teaching Fellowship (Excellence in Civil Engineering Education). June 2012. The ExCEEd Teaching Workshop is a six-day practicum that provides engineering educators with an opportunity to improve their teaching abilities. It is funded by a grant from the ASCE Foundation. Each year, about 50 applicants are selected, based primarily on the extent to which their individual needs, motivations, and commitment to attend are consistent with the focus of the workshop.
