Bio

Over the past 15 years, Dr. Alison Robertson's research has focused on elucidation of the mechanisms of toxicity and resistance, and health impacts of natural toxins and anthropogenic contaminants in marine and freshwater at multiple levels of organization (bio-molecular, cellular, organismal, population, community, and ecosystem). She has a strong interest in understanding impacts of chemical contaminants in aquatic organisms and ecosystems, particularly the sub-lethal effects on behavior, reproduction, immune system, and nervous system function.

Research Highlights:

  • Understanding the chemical ecology and mechanisms of toxin and secondary metabolite production in pelagic and benthic phytoplankton 
  • Biomolecular mechanisms and impacts of phycotoxin exposure in marine biota and humans
  • Evaluating ecological risk of cyanotoxins, ciguatoxins, and other phycotoxins on local, regional, and global scales
