Research

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.
