I am a biological oceanographer, specializing in zooplankton ecology in estuaries and coastal regions. My particular interest is in how zooplankton individuals and populations function within an ecosystem. Much of my work has focused on marine copepods, in the context of the entire pelagic food web.
Zooplankton are food for commercially important fish species, consumers of primary and secondary production, cyclers of nutrients and particles, and can be used as tracers in the ocean.
Behavior reflects both the internal physiology of organisms and the external environmental conditions in which an organism resides. Thus, studying behavior allows me to address the question of how zooplankton individuals and populations function within an ecosystem. However, plankton live in a dilute and dynamic environment, and it is not always possible to unambiguously infer whether behavior or environmental conditions are driving the observed distributions, because it is difficult to reliably sample microscopic individuals at appropriate scales. For these reasons, I have been combining various sampling, observation, and experimental techniques to tackle questions in zooplankton ecology.
In my current research, I am incorporating data collected over large spatial or long temporal scales to data on zooplankton individuals. These data are gathered using a variety of methods, ranging from high-tech acoustic and optical instruments to traditional net samples and laboratory experiments. In addition, I am using numerical models to test hypotheses about the behavior of the organisms in ways that are relevant to in situ data. In the end, this work can be put into the context of the entire ecosystem, to gain a better understanding of the ecological function of pelagic systems.
