My research focuses primarily on the ecology and physiology of filter-feeding invertebrates. Using dyed and fluorescently-labeled microbeads, I attempt to elucidate the mechanism and efficiency of particle capture and trace the path of the particle through the digestive tract.
I am also interested in using cellulose acetate electrophoresis to analyze allozymes in an attempt to elucidate information about the evolution and genetic diversity of certain invertebrate populations.
Finally, I’ve recently become interested in using molecular techniques (PCR and/or ELISA) to determine the presence of parasitic helminthes and protists.
