ResearchResearch interests include (1) the investigation of factors that shape microbial communities in aquatic habitats, (2) the study of carbon flow within the microbial food webs
Current research activity (1) biogeography of aquatic protists, (2) micropollutants as vectors of microorganisms, (3) microbial food webs in artificial aquatic systems
