Biography

I completed my Ph.D. from the College of William and Mary's Virginia Institute of Marine Science in 2009 studying the feeding ecology of mesopelagic zooplankton in the North Pacific Ocean. Upon completion of my dissertation, I moved to Moss Landing, California to work at the Monterey Bay Aquarium Research Institute as a postdoctoral fellow. There I investigated the contribution zooplankton make to the flux of organic carbon in the abyssal plain region of the deep-sea and compared these results to several climate indices as well as surface zooplankton abundances in the same region. I then completed two short postdocs at the Marine Biological Laboratory in Woods Hole, MA and Arizona State University and I am currently working on collaborative research project with both institutions. I recently joined the School of Ocean Sciences in June 2011.

Research Interests

Zooplankton are important contributors to ocean processes as they are a source of food for many marine animals and themselves graze microzooplankton, phytoplankton, and marine snow. In the upper layers of the ocean, zooplankton can repackage these particles into quickly sinking fecal pellets which are then either reprocessed by bacteria and other zooplankton while sinking or are sequestered in the deep sea as part of a process called the biological carbon pump. The focus of my research is zooplankton ecology and zooplankton impacts on particle repackaging and contribution to the biological pump as well as the impacts of climate change on zooplankton distribution, abundance, biomass, and carbon flux through the deep sea. I have experience working with measuring zooplankton distribution, abundance, biomass, feeding ecology, and fecal pellet production rates and fluxes in several locations around the world. Currently I am investigating the feeding ecology and fecal pellet production rates of zooplankton collected from the highly productive Amundsen Sea Polynya in the Antarctic as well as from the Bermuda Atlantic Time-series Study (BATS) site in the Sargasso Sea. For these projects I will be using fatty acid trophic markers, epifluorescence microscopy, and DNA-based molecular techniques such as PCR and Denaturing Gradient Gel Electrophoresis (DGGE) to determine the cyanobacteria and eukaryotic composition of their diets.
