Research Interests

My research is focused on developing methods of detection, quantification and characterization of single-walled carbon nanotubes (SWNT) in environmental media as well as determining their environmental impact in benthic estuarine systems. To investigate the direct impact of SWNT on benthic communities, I have performed toxicity and bioaccumulation studies through sediment and food exposure routes on several benthic invertebrate species. I am also interested in the effect SWNT may have on co-contaminants. Our lab has previously shown that hydrophobic organic contaminants (HOCs) sorb to the surface of SWNT. However, it is unknown whether SWNT will act as a vector or a sink for these HOCs and whether the SWNT type (semiconducting vs metallic) will impact co-contaminant sorption.
