Ari Lewis Invited to Serve on the US EPA Science Advisory Board Environmental Justice Screen Review Panel

Gradient scientist Ari Lewis appointed to US EPA Science Advisory Board (SAB) EJScreen Review Panel

[March 20, 2023, Boston, MA] – The United States Environmental Protection Agency (US EPA) recently announced appointments to its Science Advisory Board (SAB) ad hoc review panel for EJScreen, its new environmental justice (EJ) screening and mapping tool. Gradient scientist Ari Lewis, M.S., was selected to serve as one of nineteen panel members.

According to the US EPA Environmental Justice website, EJ is “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” The new EJScreen tool was developed to help US EPA meet its responsibilities toward EJ, by using the mapping and screening tool to access and compare valuable information about a specific area’s environmental and demographic socioeconomic indicators. The SAB EJScreen Review Panel is an ad hoc panel of scientific experts chosen to provide input on the methodology, calculations, and other components of the tool.

See a list of the EJScreen Review Panel members here.

US EPA established the SAB “to provide independent scientific and technical advice to the EPA Administrator on the scientific and technical basis for agency positions and regulations” under the Environmental Research, Development, and Demonstration Authorization Act (ERDDAA).

Ari Lewis is a principal with expertise in toxicology and risk assessment. She has applied her toxicology expertise across a wide range of chemical stewardship issues and is especially interested in cumulative risk assessment, which includes the consideration of non-chemical stressors (i.e., social factors) in vulnerable populations.

Please join us in congratulating Ari Lewis on this noteworthy service appointment!

Gradient Receives Best Poster Award in the Medical Device and Combination Product Specialty Section in the Society of Toxicology Annual Meeting

Gradient scientist Dr. Joel Cohen was co-author on a poster awarded best in the Medical Device and Combination Product Specialty Section category of the scientific proceedings in the Society of Toxicology 2023 Annual Meeting

[March 29, 2023, Boston, MA] – The Society of Toxicology (SOT) Medical Device and Combination Product Specialty Section has given a Best Poster Award in the Medical Device and Combination Product Specialty Section to a poster co-authored by Gradient as part of the SOT 2023 Annual Meeting. The winning poster, “Characterization of the ISO Database of Reference Chemicals for Interlaboratory Studies to Demonstrate the Applicability of OECD Methods to Assess Skin Sensitization of Medical Devices,” was authored by Christian Pellevoisin, A. Nguyen, Ron Brown, Rose-Marie Jenvert, Hervé Groux, Peter Cornelis, Michelle H. Lee, Austin Zdawczyk, Joseph Carraway, Emma Pedersen, Joel Cohen, David Waeckerlin, Audrey P. Turley, Sebastian Hoffmann, and Kelly Coleman. The poster was presented at SOT’s 62^nd Annual Meeting and ToxExpo in Nashville, Tennessee, earlier this month.

According to the SOT website, “The SOT Specialty Sections represent the breadth and diversity of the toxicological sciences by focusing on specific toxicological areas.” The Medical Device and Combination Product Specialty Section has a purpose of “providing an international forum where government, industry, and academic toxicologists can share state-of-the-art knowledge and develop new approaches for the evaluation of medical devices.”

One poster is selected to receive the Best Poster Award, Medical Device and Combination Products Specialty Section each year. Any poster accepted for presentation in the section is eligible for the Best Poster Award.

Joel M. Cohen, Sc.D., DABT is a principal scientist with specialties in computational toxicology and human health risk assessment. His primary responsibilities include non-clinical safety assessments of medical device and pharmaceutical components, consumer product safety evaluation, physiologically based pharmacokinetic (PBPK) modeling, and skin sensitization hazard and risk assessments.

Please join us in congratulating Dr. Cohen and his fellow authors on receiving this award!
