My long term goal is to understand those factors - both biological and environmental - that dictate the timing and magnitude of diatom blooms. I am particularly interested in how the extent of genetic and physiological diversity within diatom populations influences their ability to initiate and maintain the dramatic increases in cell number that are seen in coastal waters each spring and fall. The premise that underlies my research is that bloom dynamics reflect a complex interaction between environmental factors and the extent of diversity present within diatom populations. My first goal, then, is to determine just how diverse at both a genetic and physiological level - individual species of diatoms are. As I learn more about the characteristics of individual species in particular locales, I will then ask how this diversity is shaped by different environments and on different time scales. Ultimately, this should allow me to determine how population diversity is coupled to future blooming capabilities.
