John Kind, PhD, CIH, CSP

Principal Toxicologist

About Dr. Kind

Dr. John Kind is a Toxicologist and Certified Industrial Hygienist (CIH) with more than 25 years of experience helping clients with issues regarding worker health and safety, evaluate chemical exposures, understand potential health effects from environmental and workplace exposures and address complex questions of disease causation. His expertise spans human health toxicology and risk assessment, exposure assessment and dose reconstruction and industrial hygiene; and he serves as an expert witness in toxic tort litigation involving chemical exposures and environmental hazards.

At Onterris, Dr. Kind applies this expertise to human health and toxicology projects as well as chemical emergency response. As a former member of the Onterris Toxicology Emergency Response Program (TERP), he has led air monitoring and environmental sampling teams following hazardous materials incidents across the United States, providing critical exposure data to support decisions that protect workers and surrounding communities. His emergency response experience includes chemical releases involving fixed facilities, transportation, oil and gas exploration and production and landfills.

Dr. Kind earned a Bachelor of Science (B.S.) in Biochemistry-Toxicology from Murray State University and a Doctor of Philosophy (Ph.D.) in Interdisciplinary Toxicology from the University of Georgia.

Dr. Kind is an active participant in professional organizations and technical committees related to toxicology, industrial hygiene and emergency response. He serves on the American Industrial Hygiene Association’s Emergency Response Planning Guideline (ERPG) Committee which establishes short-term exposure guidelines for communities impacted by emergency chemical exposures.
