Risk e-Learning Webinar Series: Session I - Data Sharing Tools, Workflows, and Platforms

Sponsored by: NIEHS Superfund Research Program

Go to Archive

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on SRP-funded data science projects that are enhancing the integration, interoperability, and reuse of data. With these supplements, the SRP encourages data sharing among its grantees to accelerate scientific discoveries, stimulate new collaborations, and increase scientific transparency and rigor.

The first session will introduce tools, strategies, workflows, and platforms developed by SRP researchers to organize existing data obtained from measuring contaminants in an array of environmental media to facilitate interoperability. These strategies were developed to enable researchers to reuse the data to better characterize and understand contaminants present in the environment. We will also hear about the U.S. Environmental Protection Agency's (U.S. EPA's) CompTox Chemicals Dashboard, a compilation of information from many sites and databases developed to organize chemical data and address data gaps.

SRP Director William Suk, Ph.D., M.P.H., will provide an overview of the series and briefly discuss the rationale and goals of the SRP’s data science initiative.

Brittany Saleeby, trainee at the University of California, Davis (UC-Davis) SRP Center, will discuss a UC-Davis and Duke research collaboration focused on how disparate sources of high-resolution mass spectrometry data can be combined to harmonize approaches for non-targeted environmental analysis. Post-processing programs used by each lab for non-targeted mass spectrometry data resulted in dissimilar numbers of molecular features. The project’s current focus is describing the similarities and differences between analysis results and describing the chemical space that each data process is expected to recognize.

Benjamin Bostick, Ph.D., of the Columbia University SRP Center, and Tracy Punshon, Ph.D., of the Dartmouth College SRP Center, will describe the development of a biological elemental imaging database that brings FAIR principles (Findable, Accessible, Interoperable and Reusable) to an archive of elemental maps collected from model plants (Arabidopsis and rice) at multiple synchrotron facilities in the US over a 10-year period. They use an example of integrated, interoperable datasets to find parallels in the chemical processes affecting drinking water quality across widely disparate communities in Bangladesh, Vietnam and the Northern Plains region of the US.

Antony Williams, Ph.D., of the Center for Computational Toxicology and Exposure in the Office of Research and Development at the U.S. EPA, The US EPA CompTox Chemicals Dashboard website for Environmental Science Data, will focus on the CompTox Chemicals Dashboard. This free website provides access to data for ~900,000 chemicals. These data include property data, in vivo and in vitro toxicity data, exposure information and flexible searches for one chemical at a time or many thousands. This presentation will provide a basic overview of the Dashboard, its capabilities, and how it can help environmental scientists quickly source relevant data.

William Suk, Ph.D., M.P.H., is director of both the Superfund Research Program (SRP) and the Hazardous Substances Research Branch in the NIEHS Division of Extramural Research and Training. Suk has served as director of the SRP, a program established by Congress as part of the reauthorization of Superfund in 1986, since its inception. The SRP fosters interdisciplinary research approaches to address the problems associated with potentially hazardous environmental exposures. His affiliation with a number of organizations and committees include: Roundtable on Environmental Health Sciences, Research, and Medicine, Institute of Medicine, National Academy of Sciences; International Advisory Board of the Chulabhorn Research Institute, Bangkok, Thailand; and World Health Organization Consultation on Scientific Principles and Methodologies for Assessing Health Risks in Children Associated with Chemical Exposures. He is also a member of a number of trans-NIH committees. He received his Ph.D. in microbiology from the George Washington University Medical School, and his master's in public health in health policy from School of Public Health at the University of North Carolina at Chapel Hill.

Brittany Saleeby is a current trainee at the University of California, Davis SRP Center. She has a B.S. and an M.S. in Chemistry from the University of North Carolina, Wilmington (UNCW). In her time at UNCW, she was inspired by the idea of using art for education and outreach. She was integral to helping with up-cycled art galleries for the Plastic Ocean Project, setting up local compost facilities, and filled various teaching positions around UNCW and the wider Wilmington community. Her academic goal is to find ways to systematically screen contaminants in water, sediment, and plants as a way to address human health concerns that ultimately stem as a result of acute or chronic exposure. For her master's thesis and publication, which focused on non-target mass spectrometry techniques to analyze environmental contaminants, she and her team discovered a group of novel PFAS in drinking water and sediment from a nearby chemical manufacturer. They also discovered these compounds in rainwater. This discovery shifted the way the state looked for these PFAS and represented a new vector for contamination. Along with her passion for environmental policy making, she believes the importance of scientific literacy and critical thinking has become a priority for future generations, and she hopes to help prepare the next environmental activist, enthusiasts, and leaders.
