Current research questions

  • How did vegetation change in the last decades?
  • How do land ecosystems affect the carbon cycle?
  • How is vegetation affected by climate variability?
  • What are the controls on wildfire activity?
  • What vegetation properties can be derived from microwave satellites?
  • How can satellite data be used to improve global vegetation models?

Biosketch

Matthias was born in Zittau, Germany. He studied Geography (BSc) and Geoinformatics (MSc) with a focus on remote sensing and hydrological modelling at the Friedrich Schiller University Jena, Germany. He had several research stays at the Potsdam Institute for Climate Impact Research and performed his doctoral research at the Max Planck Institute for Biogeochemistry Jena. Thereby he focused on remote sensing and modelling of global vegetation trends. He received the PhD (Dr. rer. nat.) degree from the University Jena in 2015. Since 2016, Matthias is working as a PostDoc at the Remote Sensing Research Group at TU Wien. Matthias’ main research interest is the development and application of satellite data and global ecosystem models to assess the role of land ecosystems in the carbon cycle and the Earth system. Thereby he has a special focus on vegetation phenology, vegetation dynamics, and ecosystem disturbances like fires. Matthias uses a broad range of methodological approaches like time series analysis of satellite data, machine learning approaches, dynamics global vegetation models, and model-data integration approaches.
