Dr. Lindsey St. Mary is an applied toxicologist with over 16 years of experience evaluating chemical safety at the intersection of human health and the environment. She specializes in leveraging the aquatic model organisms and complementary laboratory systems to assess adverse outcomes from a wide range of pollutants, with expertise spanning molecular, analytical, and predictive toxicology approaches.

Her doctoral and postdoctoral research was conducted within international, multidisciplinary consortia under the EU Horizon 2020 framework, including the EUROPAH and PATROLS projects. These efforts advanced understanding of nanomaterial and pollutant interactions, photochemistry, and environmental health risk, using cutting-edge tools such as qPCR, GC-MS, and high-content assays. Dr. St. Mary has also collaborated with industry partners to integrate in vitro and in vivo platforms, improving early-stage prediction of chemical toxicity and supporting safer product design.

Her portfolio includes toxicological investigations across diverse contexts — ranging from immunotoxicity and developmental neurotoxicity to nanoparticle safety, high-nitrogen compounds, arsenic, and cancer-related pathways. She has contributed to high-throughput screening efforts with the U.S. EPA's TOXCast program and the National Toxicology Program's (NTP's) developmental neurotoxicant libraries, focusing on predictive models and structure — activity relationships linked to human disease.

Dr. St. Mary brings a proven track record of cross-disciplinary collaboration, assay development, and innovation to every project. She partners with clients in the environmental, pharmaceutical, and consumer product sectors to deliver actionable insights that drive chemical safety, regulatory readiness, and product stewardship.
