Main Research Interests

Stable Isotopes of the Bioelements

Methods & standardization
• State-of-the-art on-line measurement of δ¹⁸O (and δ²H) in organics, some inorganic substances and water
• Refinement of existing measurement techniques and their adaptation to new compounds
• Intercomparability and cross-validation of δ-values on the basis of standardization principles and referencing procedures
• Definition of suitable reference materials (international standard materials and local working and quality control standards) for measurement of correct δ-values
• Isolation and purification processes of specific compounds for isotopic analyses without isotope fractionation
• Comparability of isotope ratio mass spectrometric and (laser) spectroscopic methods for the determination of CO₂ and H₂O isotope ratios

Plant biochemistry / plant physiological applications
• Correlation and explanation of inter- and intramolecular isotope distributions in natural plant compounds, based on their corresponding (bio)syntheses and metabolism (knowledge on precursors and degradation products of specific compounds, on pool sizes and turnover rates)
• Interrelationship between isotope fractionation and isotope effects on specific enzymatic reactions
• Theoretical background of isotope fractionation

Coupling between biosphere and atmosphere
• Identification of biochemical response processes inside plants – mechanism and drivers
• Prediction of future impacts of global change
