The NIEHS Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2020. In this session, awardees from University of Kentucky, Oregon State University, and Baylor College of Medicine will describe their research projects, accomplishments, and next steps.

The University of Kentucky SRP Center, "Nutrition and Superfund Chemical Toxicity," explores human health challenges arising from exposure to halogenated organic substances such as polychlorinated biphenyls (PCBs), trichloroethylene, tetrachloroethene, and per- and polyfluoralkyl substances (PFAS). They conduct research on lifestyle changes such as nutrition and exercise and the relationship with pollutant exposure and disease risk. Center scientists also study remediation systems and engineering solutions for toxicant removal. The goal is to develop prevention strategies for diseases associated with chlorinated organic contaminants through a combination of enhanced remediation and healthy lifestyle components.

The Oregon State University SRP Center, "PAHs: New Technologies and Emerging Health Risks," investigates polycyclic aromatic hydrocarbon (PAHs) mixtures before and after remediation. Center scientists work to track PAH movement through the environment, measure PAH exposure in individuals located near contaminated sites, predict the products of PAH transformation during remediation, determine the toxicity of complex PAH mixtures, and link PAH exposure to health outcomes.

The Baylor College of Medicine SRP Center, "PAHs: Ultrasensitive Detection, Early-Life Exposures - Clinical Outcomes (Preterm Births, Chronic Lung Disease, and Neurocognitive Deficits), Prevention and Remediation," works in Harris County, Texas to explore maternal exposure to PAHs and the increased risk of preterm birth. They are investigating the molecular mechanisms behind the increased preterm birth risk after maternal exposure to PAH mixtures. Center scientists are also working to develop methods for detecting PAH-based compounds in air, water, and soil, remediation technologies to treat contaminated sediment, and strategies to prevent and reduce the health burden associated with PAH exposure.

Kelly G. Pennell, Ph.D., is the director of the University of Kentucky Superfund Research Program (SRP) Center, and leader of Fate and Transport of Contaminants in Aging Piping Systems Project as well as the Data Management and Analysis Core. In 2005, she earned her Ph.D. from Purdue University in civil (environmental) engineering and was a post-doctoral researcher within Brown University's SRP Center from 2005-2010. In 2010, Pennell accepted her first tenure-track faculty position at the University of Massachusetts-Dartmouth as an Assistant Professor of Civil Engineering. In 2013, she joined the University of Kentucky as an Assistant Professor of Civil Engineering and was promoted and tenured to Associate Professor of Civil Engineering in 2016. In 2015, she received a National Science Foundation (NSF) CAREER award, which is NSF's most prestigious awards in support of faculty who have the potential to serve as academic role models in research and education. Pennell's research emphasizes knowledge brokering and field studies to investigate transport of halogenated organic compounds. She has experience conducting site characterization activities at Superfund sites and developing computational tools to investigate environmental transport processes. She strives to interweave knowledge from a range of disciplines to make new discoveries that address complex environmental health burdens.

Pan Deng, Ph.D., is an assistant professor in the Department of Pharmaceutical Sciences and a co-investigator of University of Kentucky Superfund Research Program (UK SRP) Center project, Superfund Chemicals, Nutrition, and Multi-Organ Cardiovascular Risk, with project leader Bernhard Hennig. She earned her Ph.D. in pharmaceutical analysis from the Shanghai Institute of Materia Medica in Shanghai, China, and after completing postdoctoral work in the UK Resource Center for Stable Isotope-Resolved Metabolomics (RCSIRM), she joined the Hennig lab as a postdoc before accepting a faculty position in the College of Pharmacy. As a scientist trained in pharmaceutical analyses, she has expertise in the metabolism of cardiovascular drugs (amiodarone and 3-n-butylphthalide), which revealed several novel metabolites that contribute to drug efficacy and toxicity. These projects not only solidified her interest in cardiovascular disease, but also introduced her to lipidomics and metabolomics as systems biology approaches to studying disease mechanisms. Her postdoctoral research provided a unique skillset to study de novo synthesis of lipids and metabolite homeostasis in cell and animal disease models. Deng applies these skills in UK SRP Center to investigate metabolism disturbances induced by chemical pollutants and underlying cardiovascular disease risks.
