About

Lawrence McCray has been a pivotal figure in reshaping the landscape of toxicology and environmental health policy. His primary research areas encompass regulatory science, risk assessment, and the modernization of toxicity testing frameworks. McCray’s most transformative contribution is his leadership in the landmark 2007 U.S. National Academy of Sciences report, *Toxicity Testing in the 21st Century: A Vision and a Strategy*, which has amassed over 1,675 citations. This seminal work articulated a bold new paradigm—moving from traditional animal-based testing toward high-throughput, human-relevant *in vitro* assays and computational models. By championing this vision, McCray helped catalyze a global shift toward more efficient, mechanism-based toxicity assessments that reduce animal usage while improving human health protection. His work has profoundly influenced both the U.S. Environmental Protection Agency and the broader scientific community, setting a strategic roadmap that continues to guide researchers and regulators. For students and scholars, McCray’s legacy is a testament to how rigorous, forward-thinking policy analysis can drive systemic innovation in environmental health science.
