Research interests

Dr. Walker (he/him) currently focuses his research efforts on a wide range of biophysical sciences related to resource and environmental management, including anthropogenic impacts on the environment including: Monitoring, management, and mitigation of plastic and microplastic pollution; monitoring, management, and mitigation of industrial contaminants on the natural world; remediation and reclamation of contaminated sites; ecological risk assessment (ERA) of aquatic and terrestrial ecosystems; Air pollution impacts on ecological and human health; environmental effects monitoring (EEM); environmental impact assessment (EIA); and management of natural resources.
