Research
by tnash
- 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/gel electrophoresis) to determine the presence of invertebrate species in various environments.
