Amanda Reichelt-Brushett

SETAC Past President

Amanda Reichelt-Brushett’s international research profile is focused on enhancing our understanding of the sources, fate and consequences of contaminants in our environment and includes several subthemes: ecotoxicology, risk assessment, environmental management and ecosystem restoration.

She has more than 30 years of experience in academia, with a focus on undergraduate teaching and postgraduate training. Her motivation for teaching is to develop students’ critical and creative thinking for problem-solving in environmental chemistry and related science and management. She is the proud editor and co-author of a 2023 textbook titled “Marine Pollution –monitoring, management and mitigation,” an open-access textbook available online and in hard copy.
 

Gabriel A. Dedeke

SETAC Boar Member, SETAC Africa Immediate Past President

Gabriel A. Dedeke, Ph.D., is Professor of Animal Ecophysiology at the Federal University of Agriculture, Abeokuta, Nigeria. His research focuses on ecological and human health risk assessment of environmental contaminants, with particular emphasis on emerging pollutants, such as microplastics and their physiological and biomarker responses in aquatic and terrestrial organisms. He has more than 25 years of academic and research experience in zoology, environmental toxicology and ecophysiology, and has authored numerous peer-reviewed publications, book chapters and conference contributions. Dedeke was the Immediate Past President of SETAC Africa from 2024–2025. He has contributed actively to SETAC initiatives as a conference session co-chair, training instructor in ecological risk assessment and member of scientific program committees. His engagement reflects a strong commitment to advancing SETAC’s mission of promoting environmental science and informed decision-making globally. In addition to his SETAC service, Dedeke has held several academic leadership positions, including Deputy Dean of the College of Biosciences and Deputy Director of the Institute of Human Resource Development at his institution. He is dedicated to mentoring the next generation of environmental scientists and strengthening research capacity and science-policy integration in Africa and beyond.

Mark Johnson

SETAC Board Member, SETAC North America Past President

Mark Johnson served as the Director of Toxicology for the U.S. Army Public Health Center. He has held several leadership roles including as a past president of the American Board of Toxicology (ABT) and board member of the International Board of Environmental Risk Assessment (IBERA). He believes that the role of SETAC as a leader in environmental sciences is changing from one that has traditionally focused on understanding contaminants to one that has had to respond to increasingly complex emerging environmental issues that include human public health concerns. Johnson hopes to help SETAC encourage new ways to support multi-matrixed efforts to include One Health concepts in environmental risk assessment through focusing on emerging issues. He would also like to see SETAC bridge into recommending courses of action that will result in applied tools and solutions. 

Iseult Lynch

SETAC Board Member, SETAC Europe Treasurer

Iseult Lynch has a bachelor's degree in chemistry, a Ph.D. in physical chemistry and materials, and a master’s degree of business administration (MBA). She is Chair Professor of Environmental Nanosciences at the University of Birmingham, where her research focusses on the interaction of nanoscale materials of engineered, anthropogenic or natural origin with living systems such as the water flea Daphnia magna or cellular models such as zebrafish embryo cells and with co-polluting chemicals including PFAS, personal care product ingredients and more. She is a passionate advocate for women in science and for public engagement in research, and she was the recipient of the SETAC Europe Noack Laboratorien Outstanding Science Career Award in 2021 and the Royal Society of Chemisty John Jeyes award for Environmental Sciences in 2020 for her work on the environmental biomolecule corona acquired by nanoscale materials and its implications for nanomaterials fate and effects.
