My research interests are broadly in the ability to use molecular and genomics tools to answer toxicological questions (toxicogenomics). More specifically, I am interested in the effects xenobiotics have on gene and protein expression in different organisms. I am very interested in whole-genome approaches that allow the entire transcriptome to be assayed simultaneously. My research synthesizes traditional ecotoxicological concepts with cutting edge genomics tools to investigate global gene transcriptional changes in aquatic species exposed to environmental contaminants.
My lab currently focuses on two research areas. First, we are continuing to investigate the impacts of metallic nanoparticles in aquatic and marine ecosystems. Secondly, we are heavily involved in research aimed at understanding the effects of the 2010 Deepwater Horizon oil spill on the northern Gulf of Mexico. In both cases, we use a combination of molecular and whole-animal endpoints to try to assess toxicological impacts at both cellular and organism levels.
