Research

I am interested in patterns and mechanisms of biodiversity, and consequence of global change on ecosystem functioning and services. I develop theoretical models to examine how processes operating on various scales interact to regulate the dynamics of ecological systems.

During my PhD, I worked on the neutral theory of biodiversity (NTB) to explore its implications for macroevolutionary studies. NTB bridges from ecological to geologic timescales by incorporating the process of speciation in a stochastic birth-death model of population dynamics, but most studies had focused mainly on the ecological timescale. We extended NTB to include interspecific variation in per capita speciation rates, which generated two interesting patterns: a declining average speciation rate through time, and a negative relationship between species abundance and (per capita) speciation rate. These patterns are consistent with empirical data from fossil record and Panamanian tropical tree species, respectively.

Currently, I am developing a theoretical framework to understand the temporal stability of metacommunities. Stability at local and meta- scales can be linked through an additive or multiplicative term, similar to the partitioning of species diversity in space. With this framework, I further use statistical and dynamic models to investigate the effects of local competition, species synchrony, spatial dispersal, and environmental correlations on the metacommunity stability. The results will have practical implications for predicting the consequence of biodiversity loss, habitat loss and fragment on ecosystem functioning and stability.
