Curriculum Vitae (PDF)


I am an ecologist and a remote sensing researcher. My areas of expertise are ecosystem function remote sensing and terrestrial ecology, and my main research interest is in using remote sensing to study and analyse broad-scale vegetation dynamics and terrestrial carbon cycling, with particular emphasis on vegetation phenological and functional responses to hydroclimatic impacts.

My primary role in MPI-BGC is to work on a research project to investigate effects of biodiversity on ecosystem functioning by integrating multi-temporal remote sensing and in-situ measurement (oBEF-Across). This project is funded by German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig. This project is a collaborative effort among MPI-BGC (Max-Planck Institute for Biogeochemistry), UL (University of Leipzig), and UFZ (Helmholtz-Centre for Environmental Research).

Research Interests

  • Assess ecological resilience under extreme climate impacts;
  • Understand carbon-water relationships at ecosystem-level and their response to climate change and variability;
  • Remote sensing of ecosystem process and function (phenology, photosynthesis, water-use-efficiency) by coupling satellite observations with eddy-covariance flux tower measurements;
  • Retrieve spatially continuous fields of plant functional traits by linking ecological and ecophysiological theories with physical principles of remote sensing spectroscopy and radiative transfer.
