We are broadly interested in how plants respond to environment via ecological processes ranging from individual to plant community level. Both experimental and field study are combined to investigate the mechanisms and processes that plants adapt themselves to changing environment. Our current research themes focusing on tropical forest ecosystems are:
1. Mangrove ecology and carbon balance
- A long-term monitoring plot of secondary mangrove forest at Trat province, eastern Thailand (2001-present)
- The chrono-sequence mangrove plantations at Bangpu, Samutprakarn province, Thailand (2019-2021)
