Profile 【 display / non-display

  • The ultimate goal of my research is to apply scientific knowledge toward ecosystem-based management and conservation under environmental change. Recently, I am particularly interested in the consequences of realistic loss of biodiversity on ecosystem functioning and services. Field observations and experiments (mainly in arid/semi-arid ecosystems and alpine/subalpine ecosystems), simulation techniques, and analyses of large empirical datasets are in my toolbox.
