Anne Bonhoff, Global Head of Chemistry, UL Environment
Through her vision and over 25 years of expertise Dr. Anne Bonhoff develops targeted business solutions to ensure the standardization, harmonization, and quality of chemical testing for consumer goods throughout UL’s state-of-the-art laboratories. An industry thought leader, she is a recognized global expert on the topics of restricted substances, toxicology, environmental issues, ecological trends and eco-legislation. Anne designs and develops tailor-made chemical management and sustainability solutions across the entire supply chain including detox and zero discharge. She is frequently requested to present at high-profile events, and has authored several articles for publication. Anne was inducted into UL’s William Henry Merrill Society in recognition of her significant and sustained contribution to the advancement of safety science and safety engineering. Memberships include Swiss Association for Standardization (SNV), European Committee for Standardization (CEN), International Organization for Standardization (ISO), Technical Committee of Ginetex Switzerland, and American Apparel and Footwear Association (AAFA).
Bill Hoffman, Ph.D, UL Corporate Fellow
Research Scientist, Advisory Services – UL Environment
Bill manages the UL Environment science team working on the technical basis for the development of standards and guidance for standards including the green chemistry and sustainable chemistry aspects of product environmental performance, validation of claims, and product certification. His work provides a strong technical basis for product environmental performance by using a deep scientific analysis of the environmental impact of a product while also assuring companies producing the product are using environmentally progressive manufacturing methods. Bill is member of the William Henry Merrill Society, a UL Corporate Fellow.
Before joining UL Environment, Bill was responsible for strategy and deployment of sustainability services and worked on the development of several specifications including standards governing the chemical content of products and was heavily involved in external standardization efforts for environmental issues in electronics.
Bill holds a BS in Chemistry from Southern Illinois University, and a Ph.D. in Physical Chemistry from Illinois Institute of Technology.
Elliott Horner, Ph.D
Lead Scientist – UL Environment
Dr. Horner directs the mold laboratory for UL Environment. He has conducted research on: mold development on building materials, simulated water losses, microbial volatile organic compounds (MVOCs), fungal allergens, aerobiology monitoring, ultrafine particles, mold growth on latex paint and other materials, soil and root fungi in trees, field surveys of residential indoor air and microbial contamination in buildings. He has provided expert testimony for both plaintiff and defense. He developed and taught US Environmental Protection Agency sponsored training programs on sampling bioaerosols and indoor mold and has written more than 37 peer reviewed research papers, 10 book chapters, 8 reviews, and numerous other publications and conference proceedings.
Xue Wang, Ph.D
Project Coordinator, Advisory Services – UL Environment
Dr. Xue Wang has more than four years of experience in environmental sustainability science. As a Project Coordinator at UL Environment, her main responsibilities include developing innovative claims and environmental claim validation procedures, and conducting scientific research to support consulting and advisory projects.
Her dissertation research focused on the quantification of the environmental risks and opportunities for end-of-life electronic products. Her areas of expertise include life-cycle assessment, sustainability metrics, risk assessment, nanoparticle exposure assessment, multi-criteria decision-making analysis, energy efficiency, material flow analysis, and economic analysis.
Xue earned her Ph.D degree in Sustainability from Rochester Institute of Technology (RIT) in June 2014. She also holds a Master degree in Applied Statistics from RIT.
