Processes occurring in the larval phase of fishes play an important role in determining the degree of population variability in the adult phase. However, due to the limitations of traditional plankton sampling equipment, many physical and biological processes affecting larval fish survival are under-studied in the field. My research focuses on using an In Situ Ichthyoplankton Imaging System (ISIIS) to study fine scale (centimeters to tens of meters) distributions of larval fish, prey items (small copepods and appendicularians), and planktonic predators, and how these distributions relate in time and space. I am also interested in how mesoscale features, such as fronts, eddies, and internal waves influence the patchiness of plankton. With the use of ISIIS, we have a unique opportunity to quantify plankton densities in a variety of organisms that are under-sampled in net systems (e.g. bongo and MOCNESS), such as ctenophores and siphonophores, which are important predators of larval fishes. We have deployed ISIIS in different locations including Monterey Bay, Georges Bank, the Straits of Florida, and offshore of San Diego. On a personal note, I enjoy sports, rock music, and living in the great city of Miami.
