Austin Gray

Biological Sciences

Dr. Gray’s expertise lies in the fields of aquatic ecology and toxicology. His research is focused on investigating the combined effects of environmentally relevant levels of multiple contaminants (e.g., pesticides, pharmaceuticals and personal care products, micro plastics, and endocrine-disrupting chemicals) on aquatic organisms and ecosystems.

By joining the Global Change Center, Dr. Gray looks forward to collaborating with colleagues across the university to address the environmental, health and societal challenges posed by emerging contaminants. As an early career scientist, he is also eager to engage with IGC Fellows to share his more recent experiences via mentorship on topics such as science communication, social media strategy, and fellowship or grant funding applications.

In 2020, Dr. Gray obtained his Ph.D. in environmental health science from The University of North Carolina at Greensboro, where he studied the distribution of antibiotics in urban and rural streams and groundwater in the Piedmont of North Carolina. Previous investigations have also assessed the developmental and mechanical effects of micro plastics on estuarine organisms, as well as the toxicity of “green” home and personal care product on larval freshwater and marine organisms.

Dr. Gray currently serves on the Carolina Society of Environmental Toxicology and Chemistry (SETAC) Board of Directors, and also serves as Co-Chair and Co-Founder of the SETAC North America Inclusive Diversity Committee.
