Dr. Alvina Mehinto is the head of the Toxicology Department at the Southern California Coastal Water Research Project (SCCWRP), where she oversees a variety of projects related to molecular toxicology, traditional toxicity testing, and ecological risk assessment. Her research focuses on the linkage between exposure to specific stressors (e.g. emerging contaminants, plastics) and effects on health of aquatic organisms, and on the development of molecular screening assays – namely bioanalytical tools and RNA-based biomarkers - for monitoring the impact of chemical stressors in fresh- and coastal waters, recycled waters, and sediment.

She received her B.S. in marine biology from the University of Portsmouth in 2005 and Ph.D. in biological sciences from the University of Exeter in 2010. She joined SCCWRP in February 2013.
