Bio
Dr. LaPoint has primary research and teaching interests in ecological risk assessment, contaminant effects on freshwater aquatic communities (specifically in how metals and organic contaminants affect benthic population dynamics and freshwater fisheries). In addition, research on the consequences to fish and aquatic invertebrates of urbanizing watersheds, including consequences of water reuse. Aspects of water reuse include the use of return flows from agriculture and municipalities.
