Jordan Kozal, PhD

Jordan Kozal, PhD, Health Scientist. Dr. Kozal’s primary areas of training and expertise are toxicology and ecotoxicology, as well as human health risk and environmental risk assessment. Dr. Kozal completed her PhD in Environment with a Certificate in Integrated Toxicology and Environmental Health at Duke University’s Nicholas School of the Environment. Dr. Kozal’s research focused on the role of mitochondria in the maternal and cross generational toxicity of polycyclic aromatic hydrocarbons, with important applications in organismal ecological fitness and insights into human disease etiology. Jordan’s dissertation research and collaborations were interdisciplinary in nature, involving aspects of biochemical and molecular mechanisms of toxicity, effects of chemical mixtures, interactive effects of chemicals and other natural or anthropogenic stressors, and mechanisms and consequences of evolutionary adaptation to chemicals. At ChemRisk, Dr. Kozal’s primary practice areas include semiconductor chemicals, herbicides/pesticides, microplastics, ethylene oxide, and consumer products. Dr. Kozal has published multiple abstracts and peer-reviewed publications on various toxicology, ecotoxicology, and risk-related topics.

Ania Urban, PhD, MPH

Ania Urban, PhD, MPH, Senior Supervising Health Scientist. Dr. Urban completed her PhD in Environmental Health Toxicology from the University of Minnesota. Her primary area of expertise is in carcinogenesis and chemoprevention. Dr. Urban’s doctoral work focused on elucidating the role of DNA adducts in lung cancer formation. During her doctoral work she used both in vivo and in vitro models to investigate the formation and repair of DNA adducts following exposure to tobacco-specific nitrosamines. She developed quantitative analytical techniques for the detection of DNA adducts and metabolites formed from nitrosamine exposure. Dr. Urban also received an MPH in Environmental Health Sciences, during which time she developed methods to detect the formation of urinary metabolites following exposure to polycyclic aromatic hydrocarbons (PAHs). She has extensive experience in the development of analytical techniques for the detection of metabolites and DNA adducts, as well as in the design of large-scale animal studies. Dr. Urban’s current primary areas of practice include researching and conducting quantitative risk assessments of a variety of chemicals including asbestos, diacetyl, talc, nitrosamines including n-nitrosodimethylamine (NDMA) and n-nitrosodiethylamine (NDEA), constituents of wildfire smoke, and various ingredients in personal care products. She has also conducted risk assessments related to California’s Proposition 65.
