The Ecotoxicology and Pathophysiology of Aquatic Organisms research program investigates organism responses and pathophysiology across levels of biological organization.  We are particularly interested in evaluating expression profiles of target gene transcripts that are involved in biological processes and evaluating how these profiles relate to activity of gene products and higher order responses at tissue (histopathology), organism (behavior, reproduction), and population levels. 

Manipulations include stressors such as toxicant exposure, particle exposure (engineered nanomaterials, microplastics, nanoplastics), pathogen exposure, thermal stress, and alterations of water chemistry (e.g. acidification). Research organisms include mostly fresh and saltwater fishes but also various aquatic invertebrates.  We are especially interested in contaminant issues that impact the ecological services of aquatic environments in vulnerable ecosystems and working with stake holders to manage these issues.
