Professional Profile

Dr. Laurie Haws is a Managing Principal Scientist with ToxStrategies, Inc., and is based in Austin, Texas. She is a board-certified toxicologist with over 26 years of experience in the areas of toxicology, human health risk assessment, risk communication, and scientific and regulatory policy.

Dr. Haws has substantial experience evaluating potential human health risks associated with exposures to a wide variety of chemicals and metals present as additives, ingredients, or contaminants in foods, consumer products, personal care products, pharmaceuticals, medical devices, and environmental media (air, water, soil, and sediments). She also has broad experience conducting complex, multipathway risk assessments to address concerns about stack and fugitive air emissions associated with a variety of industrial operations. In addition, Dr. Haws has extensive experience assessing potential human health risks associated with personal, occupational, and community-wide exposures to air contaminants, particularly associated with chemical, petrochemical, and shale gas exploration and production activities. Dr. Haws has experience designing, conducting, and interpreting data from biomonitoring studies, and is adept at using such data to assess concerns regarding potential exposures. She is skilled at evaluating data concerning modes and mechanisms of action and in using this type of data to make determinations regarding the relevance of findings to humans, as well as in conducting weight-of-evidence analyses for both cancer and non-cancer risk assessments. Dr. Haws has employed these skills to develop state-of-the-science toxicity values and associated media-specific screening levels for a variety of toxicants. She has conducted studies evaluating metabolism and disposition of a variety of halogenated aromatic hydrocarbons and has experience designing and implementing both cross-fostering and developmental toxicity studies.

While Dr. Haws is an internationally recognized expert on the toxicity of and exposures to dioxin-like compounds, she also has conducted assessments of many other toxicants throughout her career, including chlorinated hydrocarbons, aromatic hydrocarbons, glycol ethers, other organic solvents, volatile organic compounds, pesticides, phthalates, metals, persistent organic pollutants, and others. She is knowledgeable about a number of state and federal regulatory programs and has assisted in the preparation of reports for submission to regulatory agencies such as the FDA, EPA, and California’s Proposition 65 program. Dr. Haws also has substantial experience working with federal, state, and local government agencies, industry, trade associations, legislative representatives, the media, and members of the general public on matters related to the toxicity of chemicals encountered in our daily lives.

Dr. Haws has a diverse background, having worked as a researcher, a regulatory toxicologist with a government agency, and a scientific consultant. In fact, a substantial portion of her career has been spent in the government sector, both as a researcher and most recently as a manager in the Toxicology and Risk Assessment Section at the Texas Commission on Environmental Quality (TCEQ). In her position with the TCEQ, Dr. Haws was responsible for overseeing all human health risk assessment activities and was one of the primary authors of the agency’s comprehensive risk-based corrective action rule (the Texas Risk Reduction Program [TRRP] rule).

Dr. Haws is an author on over 47 peer-reviewed publications and has presented at numerous scientific conferences. She is an active member of numerous professional societies, including the Society of Toxicology, Society for Risk Analysis, Toxicology Forum, American College of Toxicology, and the Regulatory Affairs Professional Society. Dr. Haws has served on numerous elected and appointed committees within the Society of Toxicology, including serving on Council, as well as serving as president of the Risk Assessment Specialty Section and the Women in Toxicology Special Interest Group. In addition, Dr. Haws has served on a number of scientific panels, technical workgroups, and advisory committees, including the World Health Organization’s Toxic Equivalency Factor Review Panel. She also served as the Chair of the International Symposium on Halogenated Persistent Organic Pollutants held in San Antonio, Texas, in September 2010. Currently, Dr. Haws is serving on the Exposure and Human Health Committee of the USEPA’s Science Advisory Board.
