Roles of marine microorganisms (including bacteria, archaea, viruses, and protists) in food webs. Human pathogenic viruses and bacteria in seawater. Diversity of all these organisms, especially as studied by molecular biological techniques (particular interests in coral reef areas and deep sea). Factors controlling these systems. Effects of (and on) global change.
Identification of microorganisms including bacteria, archaea, viruses (non-cultivation, DNA or RNA based methods)
Measurement of microbial abundance and activity
Detection and measurement of microbial contaminants, including human pathogens, in water and air
