Dr. Kristian Fried holds doctoral degrees in both chemistry and toxicology. He is certified by the American Board of Toxicology and by the European Register of Toxicologists. Dr. Fried has more than 15 years of hands-on work experience in the chemical and consumer product safety and stewardship sectors and is an appointed Adjunct Assistant Professor at Rutgers University where he teaches human risk assessment.

Dr. Fried’s passion for applying insights from chemistry to toxicology began during his academic training, which he pursued across multiple geographies. Lessons from the first-time synthesis of a novel dioxin analogue and its characterization, including steric modeling, motivated him to study biological effects from receptor binding to in vitro responses and culminated in the identification of potential therapeutic applications based on nonclinical models.

In his ensuing industry career, Dr. Fried devoted his expertise to human health sciences, environmental toxicology and fate, as well as applied regulatory toxicology. His professional practice extends from patient safety and the investigation of down-the-drain fate and environmental effects of drugs to the safety of oral care products as well as other consumer goods such as cleaning products, cosmetics, flavors, and fragrances. Furthermore, Dr. Fried has assessed and advised on occupational safety regarding workplace exposures in the chemical and petrochemical sectors and the mining industry.

His leadership roles in corporate toxicology honed Dr. Fried’s strong analytical and strategy skills, which he also applied in the management of consortia work regarding scientific fundamentals as well as ingredient defenses. He has firsthand expertise with the European Chemicals Agency, the European Commission’s Scientific Committee on Consumer Safety, FDA, EPA, and California’s Office of Environmental Health Hazard Assessment.

Dr. Fried currently leads Integral’s Product Stewardship and Liability group, where he serves as principal in charge, project manager, or senior technical reviewer for various projects serving consumer products consortia and industry clients.
