  • Morphological and molecular phylogeny of the polycytopharyngeal ciliate Pycnothrix monocystoides Schubotz, 1908, 2020, Aquatic Ecosystem Health & Management

Their research topics broadly covered:

  • Protist diversity and phylogeny
  • Microbial community ecology and physiology
  • Methane hydrates and related phenomena
  • Legume nitrogen fixing symbiosis

The scientist frequently collaborated with colleagues in their field, including Peter Vďačný, Khaled A. S. Al-Rasheid, Michaela C. Strüder-Kypke, and Denis H. Lynn.
