Research Interests

I am interested in global carbon cycling and climate change, especially in high latitudes, which have experienced faster warming. Boreal forests contain large amount of soil carbon which is preserved in permafrost. The degradation of permafrost may be accelerated by the removal of surface organic layer (SOL) through boreal forest fires. However, this effect of boreal forest fires has never been considered in any terrestrial ecosytem models.

My current research is to investigate the effects of changing thickness of SOL on permafrost degradation and on soil organic matter decomposition through considering removal of SOL by forest fire and regrowth of SOL, using Terrestrial Ecosystem Model (TEM).
