Interests

Research interest

I am interested in the cross-cutting science at interface of meteorology (wind, rainfall, snow, etc.), forestry, and soil science from ecohydrological and geomorphological perspectives. Specific interest is raindrops, rainfall partitioning process by forest canopy, tree sway and breakage mechanism by fluid (wind, avalanche, and tsunami), and soil erosion in mountainous forest area.

Field
  • Ecohydrology
  • Hydrogeomorphology
  • Tree Biomechanics (and Ecomechanics)
