He currently works at the laboratory of Ecotoxicology of the Research Center for Food and Development (CIAD). His research is focused on assessing the exposure and effects of contaminants on coastal and marine life. Recently, his group has also been involved in developing waste management technologies to promote circular economy initiatives in urban and rural landscapes. He loves diving and always imagined himself studying the sea like Jacques Cousteau, but pollution got in his way. He has been involved in SETAC activities for almost 20 years, particularly at the beginning of the formation of the Mexico Chapter of SETAC North America.   

Susanne received her B.S. from Elizabethtown College, a small liberal arts college in central Pennsylvania, and soon after, she moved to Washington, D.C., to work for The Nature Conservancy, where she realized her career would be centered around the study and protection of the environment. Susanne earned a M.S. in Environmental Science and Policy from Johns Hopkins University, then a Ph.D. in Toxicology and Pharmacology from the University of California Davis. After a few years as an Assistant Professor at the University of North Carolina Wilmington, she moved west again to Oregon State University, where she is now faculty in the Department of Environmental Toxicology and Chemistry. Brander’s research is funded by NOAA and the USEPA, and it encompasses the fields of toxicology, endocrinology and ecology, integrating molecular approaches – such as evaluations of gene expression and DNA methylation – with measurements at the organism- and population-level in fish and invertebrates.

Katie is an ecotoxicologist at Bayer Crop Sciences, with previous industry experience at Dow Chemical for more than twelve years. She received her Ph.D. from Michigan State University and began her career as a consultant followed shortly after as an assistant professor of biology and chemistry at a small college in Central Florida. Her areas of expertise include aquatic toxicology, ecological risk assessment, endocrine disruption, microplastics and bioaccumulation science. She first became involved in SETAC as a graduate student in the late '90s, and since that time, she has regularly participated in SETAC activities and groups on the regional level and in several geographies. Her goal as a board member is to give back to the scientific society that's been so important to her, and she believes that SETAC should be moving toward greater inclusion and diversity and adopt innovative approaches to advancing science education and communication. In her free time, she is busy raising two teenagers in Midland, Michigan, and taking care of too many pets (2 dogs, 2 cats, 2 rats, 4 lizards, and two freshwater fish aquaria!)

Michelle Hornberger is a research scientist at a federal agency and is the project lead for assessing ecological risk related to metals in mine-impacted ecosystems. Michelle received her doctorate in Ecology from UC Davis and focuses her research on the interaction between environmental metals exposure and biological uptake. She has been a SETAC member since 1992 and has participated in several SNA sub-committees, including the Career Development, Membership and Meetings Committees.

Sarah obtained a B.S. in Environmental Science at University of Guelph and a master’s degree in environmental toxicology at the University of Saskatchewan. After her Ph.D., Sarah started as an Ecotoxicologist in the Risk Science Team of Shell Oil Company in 2008 in Houston, Texas, where she still works as a Senior Ecotoxicologist. Sarah’s role in Shell is to provide subject mater expertise on the environmental fate and effects of chemicals and contaminants and develop research solutions for Shell’s businesses globally. Sarah is adjunct faculty at four universities – University of Saskatchewan, University of Alberta, Clemson University and, most recently, Texas Christian University – and has served on multiple student thesis committees, thereby bringing both academia and industry experience to the board. As a Canadian/US dual citizen and actively supporting research programs in both countries, Sarah believes she can offer perspective on issues that supports the majority of North American SETAC members.

Latonya is an aquatic toxicologist at the University of Cincinnati. Her research focuses on endocrine disruption and adaptation in freshwater fish and invertebrates exposed to endocrine disrupting chemicals and mixed contaminants. She has been a member of SETAC since 2010, when she was a graduate student earning her Ph.D. from the University of Louisiana at Lafayette. She joined several different committees and focus groups at her first SETAC North America conference in Portland, Oregon, and has been an active member ever since, taking an active role in many SETAC groups and committees. She has also been a mentor and speaker at SETAC annual meetings. As co-founder and co-chair of the Inclusive Diversity Committee, she is extremely passionate about diversity (racial, ethnic, sexual orientation, physical abilities, beliefs, etc.) and inclusion issues. This will remain a priority area for her until it is no longer an issue in SETAC.

Nile received a B.S. degree from the University of Nebraska-Kearney in biology with a wildlife emphasis and a M.S. from the University of Missouri in Fisheries Management. Nile has worked with a variety of other organizations, both nationally and internationally, to develop sediment quality guidelines that can be used to predict the incidence of toxicity in sediments as well as working with ASTM and USEPA in developing standard methods for conducting toxicity tests with contaminated sediments. Nile’s current research is primarily focused in evaluating toxicity and effects of hazardous algal blooms on freshwater fish and invertebrates and working on developing a bait food for eradicating invasive carp. He has published 94 peer reviewed articles or final reports.

Patricia is a Professor of Aquatic Pollution and Ecotoxicology at Metropolitan Autonomous University (UAM) in Mexico City. She received a B.S. in hydrobiology, a M.S. in experimental biology from UAM and a Ph.D. from Miami University of Ohio. Her research has focused on the effects of metals and PAHs on aquatic invertebrates. Patricia founded the SETAC Mexico Regional Chapter and was elected as their first president and subsequently received the Eugene Kenaga SETAC Membership Award in 2012.

Cynthia has been a SETAC member since 2002 and quickly found a professional home among interesting members. Collaborating with others, she worked to bring the first debates on uncertainty, sustainability and climate change to SETAC meetings. Cynthia has chaired the Decision Uncertainty Working Group (under the Ecological Risk Assessment Interest Group) and the SETAC Science Committee. She was a founding member of the Sustainability Within SETAC (SWS) Interest Group. Traditionally trained as a bench scientist in biology and biochemistry, Cynthia has spent her 35-year career applying these sciences, first in toxicology and then in multi-criteria environmental policy analysis. With each educational and career move, her primary focus changed from conducting good science, to assuring the presentation of relevant science to decision-makers, to integrating science across scientific disciplines and understanding decision-making context that is shaped by diverse social and cultural perspectives for multi-criteria decision-making.
