Dr. Edward (Ed) LeCluyse is currently a Senior Research Investigator in the Institute for Chemical Safety Sciences at The Hamner Institutes of Health Sciences. Dr. LeCluyse leads a program initiative to identify and develop novel in vitro hepatic model systems to examine cellular responses to drugs and environmental chemicals that target known toxicity pathways. The focus of his research efforts has been to create more organotypic, physiologically-relevant in vitro models that integrate the architectural, cellular and hemodynamic complexities of the liver in vivo.
