Biography and Research Information

OverviewAI-generated summary

Orithea Z. Regn's research investigates the toxicological effects of environmental contaminants, particularly insecticides, on aquatic organisms and the implications for human health. Her work has focused on the culturing characteristics and toxicant responses of *Ceriodaphnia dubia*, a common species used in toxicity testing. Regn has also studied the acclimation capacity and thermal tolerance of madtom catfish species endemic to the Ozark–Ouachita Mountain region.

In addition to ecotoxicology, Regn has explored alternative methods for toxicity testing, including the use of light-emitting diode (LED) light for organism culturing and reference toxicity testing. Her research is supported by federal funding, including a National Science Foundation grant for the acquisition of an UHPLC-TQ and DESI system to facilitate interdisciplinary ecotoxicological and analytical research at Arkansas State University. She collaborates with researchers at Arkansas State University, including Brook L. Fluker, Brittany L. McCall, Jennifer L. Bouldin, and Victoria R. Lydy, on shared publications.
