Research Area: Organic Geochemistry, Geobiology, Biogeochemistry

I work in the following areas. For more details please see my other website.

  1. Changes in molecular structure and composition of biopolymers and lipids in terrestrial and marine organisms in different Pressure-Temperature conditions.
  2. Molecular structure, composition and formation pathway of kerogen in important source rocks.
  3. Biogeochemistry of fossils and associated sediment from important Fossil Lagerstatten.
  4. Development of analytical and experimental techniques.
  5. Reconstruction of source input and assessment of thermal history of sedimentary organic matter using biomarkers.
  6. Biomolecular Paleontology.
  7. Experimental Taphonomy.
