I have conducted studies on rainfall-runoff processes and biogeochemical cycles in forest ecosystems applying long-term field observations more than 20 years especially using isotopic tracer applications and state-of-the-art techniques.
Recent interest is describing the effects of bedrock groundwater dynamics on the water budget, mean residence time, and nutrients and materials cycles in the forest ecosystems.
The long-term field observation, which can reveal that the forest growth, maturity, and degradation will be reflected on the ground- and stream water chemistry, is the foundation of all of my works.
In addition to the long-term observation, I have been applying some new techniques such as high-frequency water quality sensors and/or thermal infrared imaging camera to monitor the abrupt responses of discharge, nutrient, and sediment transport to the extreme storm events.
Based on the combined approach of the long-term observation and high-frequency intensive monitoring of hydro- biogeochemical responses, I have been considering the effects of climate change and increasing extreme events on the vulnerability or resiliency of forest ecosystems.
