Research

Earthquakes generate strong ground motions that ultimately lead to the destruction of existing infrastructure and loss of life, and are a major threat to sustainability. The 2015 Nepal earthquake killed approximately 9,000 people and injured 22,000, and the 2011 Japan earthquake and tsunami resulted in nearly 16,000 deaths. Recently, there is increasing attention to earthquake hazards in Korea as the 2016 Gyeongju earthquake injured 48 people, and caused damages to structures and architectural heritages with a loss estimate of about one billion won.

My research up to this point has focused on predicting the hazards from earthquakes and secondary effects by seismic hazard analysis, site response analysis, slope stability analysis, liquefaction analysis, and soil-structure interaction analysis. These efforts can facilitate designing new earthquake-resistant structures and seismically mitigating existing structures. I would like to continue to advance the state of practice in this area while exploring additional research through interdisciplinary collaboration.
