Superfund Research Program Progress in Research Webinar Part 4: Boston University, Texas A&M University, and University of California, Davis
Sponsored by: NIEHS Superfund Research Program
This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees Boston University, Texas A&M University, and University of California, Davis, will describe their research projects, accomplishments, and next steps.
The Boston University SRP Center explores the long-term impacts of early life exposure to Superfund chemicals in humans and wildlife. Their work focuses on contaminants including polychlorinated biphenyls and tetrachloroethylene found in and around the New Bedford Harbor Superfund site and in drinking water of nearby communities.
The Texas A&M University SRP Center focuses on developing comprehensive tools and models for addressing exposure to mixtures during emergency-related environmental contamination events. The researchers are evaluating the complexities of hazardous chemical exposures, potential adverse health impacts, and potential hazards of exposures to complex mixtures through projects that derive from a case study utilizing the Texas Galveston Bay area.
The University of California, Davis SRP Center uses integrated chromatographic, biosensor, and cell-based technologies to detect and identify contaminants and develop innovative approaches for bioremediation. The Center is expanding the use of transcriptomics, proteomics, metabolomics, and integrated bioinformatics technologies to discover new mechanisms of action of hazardous materials and biological markers for their action and to connect hazardous substance exposures to organism level effects.

Presenters:
David Sherr, Ph.D., Boston University (dsherr@bu.edu or 617-638-6463)
Since 1993, David Sherr, Ph.D., and his research team have conducted research on how common environmental pollutants, such as dioxins, polycyclic aromatic hydrocarbons and PCBs, adversely affect the growth and behavior of several different types of normal and malignant cells. In previous work, the Sherr laboratory studied how environmental chemicals affect the development of the immune system. His laboratory demonstrated that aromatic hydrocarbons compromise the function of bone marrow cells required for the development of antibody-forming cells. These cells are critical for immune protection against viruses and bacteria. More recently, Sherr's laboratory has focused on the molecular mechanisms that initiate and maintain breast cancer and on the effects of environmental chemicals on these processes. The laboratory has shown that a cellular protein receptor, referred to as the aryl hydrocarbon receptor (AhR), plays an important role in the initiation and progression of human breast cancer. A new area of study in Sherr's laboratory is the analysis of the role of the AhR in blood cell development. Sherr is the director of the Boston University SRP Center and the Immunology Training Program, and a member of the Amyloid Treatment Research Program, the BU Cancer Center, the Hematology/Oncology Training Program, and the BU Hormone-dependent Cancer Center.

Dr. Heiger-Bernays leads the Research Translation Core (RTC) for the NIEHS-supported BU Superfund Program. Her work on the RTC is focused on technology and information transfer of the science to multiple audiences, including environmental regulatory and health agencies as well as with advocacy groups and community groups. Her research and teaching include a focus on effective ways to translate findings from the laboratory to multiple audiences. Heiger-Bernays' overall objective is to engage communities in their understanding and mitigation of environmental health risks. She currently serves as a member of the Massachusetts DEP Waste Site Advisory Committee and the Science Advisory Board for the Toxics Use Reduction Institute and is chair of her local board of health. In 2015-2016, she was an AAAS Science and Technology Fellow hosted in the Office of Science Coordination and Policy at the US EPA, working in the Endocrine Disrupting Screening Program.
