Research Projects

With an apparent regional and global increase in the frequency, expansion and intensity of harmful algal blooms (HABs) in freshwater, estuarine and marine waters, there is an urgent need to 1) better understand anthropogenic and natural drivers of toxin production, accumulation, transport and degradation, 2) characterize emerging HABs and phycotoxins, 3) develop tools to detect algal toxins in seafood and drinking water supplies, and 4) predict how HAB dynamics and toxicity might be altered by expanding coastal development and climate change. Our interdicisplinary research team, therefore, investigates multiple taxonomic groups and their phycotoxins in coastal watersheds, along the freshwater-estuarine-oceanic gradient, pushing HAB research into the direction of multiple stressors, multiple HABs and toxins, all acting on an interconnected system in a changing world.
