My research goals are to understand the ecological and evolutionary processes shaping genetic diversity in the plankton and to examine how those processes affect plankton community structure, function and productivity. Ecologically important events such as environmental adaptation, sexual reproduction, rates of migration and fluctuations in population size are recorded in the DNA of every individual. My approach is to identify and exploit the genetic variation that exists within and between individuals to examine how plankton respond to their environment. I use techniques from the fields of population genetics, genomics, biostatistics, physiological ecology and physical oceanography to examine 1) population genetics and biodiversity of phytoplankton and zooplankton, 2) metabolic responses to nutrient stress in phytoplankton, 3) prey selection in zooplankton, 4) adaptive evolution and speciation of plankton and 5) the relative roles of dispersal and natural selection in determining the structure and productivity of planktonic communities.
