Research profile

My interest is in the application of modeling techniques in interdisciplinary studies. Understanding the agroecology of plant cultivation in temperate, tropical, and arid environments is the major focus of my work. I am currently working as a system modeler in two large collaborative research projects. Identifying patterns in soil-vegetation-atmosphere systems and trying to understand their interrelations is the focus of one collaborative research (TR32 SFB). The other assesses environmentally friendly options for food production in East-African wetlands (GlobE Wetlands). Interfacing system biological computation methods with growth modeling is an upcoming activity. 

I have conducted energy-balance studies in plant and tree canopies, simulated growth of the most important crops using contemporary crop models, and analyzed agricultural production systems in semi-arid and tropical regions. I recently invested considerable amount of time in validating and improving measuring techniques for generating high quality data required for proper model parameterization, calibration, and validation. Designing a canopy chamber for measuring plant stand gas-exchange and improving the heat-balance method for measuring sap-flow in wheat are recent contributions.
