Research

Research 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

Recent projects
