Research Experience
Landscape Evolution by Quaternary Fault Movement (Mentor: Dr.with Jin-Hyuck Choi Kobayashi ), Nov., 2022–Current
· Conducted GPR, 3D trench, and Geological modeling at Central Yangsan, Korea (Tools: Fortran90, Gempy).
Estimation of the lateral displacement of faults (Supervisor :Jin-Hyuck Choi, Mentor: Takao Kobayashi), May, 2020-Feb., 2021
· Tried to image paleo-channels cut by paleo-earthquakes from GPR investigation in order to assess the lateral displacement of faults (Tools: Fortran90 and Python).
Investigation of a Possible Lunar Lava Tube (Mentor: Takao Kobayashi), Dec., 2016–Aug., 2017
· Found an anomalous discrepancy at a certain possible lunar lava tube by comparing the Kaguya surface range data with the simulated surface range data (Tools: Fortran90, Matlab, and QGIS).
Preparations for Korean Lunar Mission (with Kyeong Ja Kim), 2015–2017
