  • My research area focuses on nitrogen and carbon cycling in terrestrial ecosystems under global changes. In particular, I study the fates of deposited nitrogen in forest ecosystems to investigate the retention in the system and its partitioning among plant and soil pools and its implication for key ecosystem services such as carbon sequestration, I use 15N tracer experiments to trace the fates of deposited nitrogen at various spatial and temporal scales.
