Research Interests


Current research is focused on Arctic marine microbes, especially planktonic microorganisms (phytoplankton and other protists, archaea and bacteria). These organisms are responsible for global carbon and mineral cycling on a planetary scale. My laboratory addresses such questions as: How many micro-organisms are there in the water column? What is their genetic and metabolic diversity? What factors determine growth and mortality?
