Areas of research focus

  • Ecology of bacteria and archaea
  • Bacteria in forest soil and aquatic sediment
  • Bacteria in the nitrogen and methane cycle
  • Molecular DNA analysis of microbial communities
  • Microorganisms, vaccination, and human culture

Bacteria are the most ancient form of life on Earth. They are also the ancestors of mitochondria and chloroplasts, which are key organelles in plants, fungi and animal cells. They also play a key role in biological communities as the main catalysts in the cycling of organic matter in forest soil, freshwater and marine sediments. Furthermore, some bacteria are important in the production of food while others may cause foodborne diseases and epidemics in human communities.

My research interests are on the various factors that control the activity and diversity of microbial communities in soil or sediments, not only in natural ecosystems but also in anthropic systems. A combination of methods ranging from classical microbiology and analytical chemistry to molecular genetics are used to study bacteria in their natural habitat.
