Professor and Head of Research Group of Forest Ecology & Modeling in South China Botanical Garden of the Chinese Academy of Sciences, Guangzhou, China. Research interests: 1) To investigate the inter-annual growth response of trees and forests to climate change/warming in the northern hemisphere using dendrochronology and forest ecology. 2) To monitor intra-annual xylem formation and tree phenology (budburst, flowering and shoots/branches extension) in response to climate change and further clarify the potential mechanisms behind it. 3) To quantify the potential relationships between tree growth and environmental factors using linear/nonlinear and mixed models, and further assess the potential changes in forest growth, composition and structure under global change.
