Research Interests

The research in our lab focuses on basic ecology of terrestrial plants — how abiotic and biotic factors influence the diversity, distribution and life-history of species. I am interested in utilizing molecular markers to solve ecological questions as well as bottom-up approaches that considers population-level processes to explain community- or ecosystem-level phenomena. My past research includes the dynamics of plant populations and communities in terms of their responses to natural or human-induced changes in environment; the consequences of plant genetic diversity for ecosystem functioning; and the ecology and evolution of life-history strategies under heterogeneous and changing environment. I have been mainly focusing on temperate forest ecosystems, using a combination of field survey, genetic analysis and modeling of population dynamics. For more details please look through some of my publications below.

Keywords — Clonal growth, ecosystem functioning, forest plants, habitat fragmentation, genetic diversity, life history, mating system, population dynamics
