INSTITUTION AND LOCATION DEGREE (if applicable) Completion Date MM/YYYY FIELD OF STUDY Lawrence Technological University, Southfield, MI BS 05/1997 Civil Engineering Rose Hulman Institute of Technology, Terre Haute, MS 05/2001 Environmental IN Engineering Purdue University, West Lafayette, IN PhD 12/2005 Civil Engineering Brown University, Providence, RI Post-doc 07/2008 Chemical Engineering A. Personal Statement I am well-qualified to serve as a Co-Investigator in this collaborative research project to establish sciencebased methods for improving the accuracy of exposure risk estimates for both chlorinated volatile organic compounds (CVOCs) and perfluoroalkyl acids (PFAAs). I have over 12 years of experience working within multi-disciplinary research centers and drawing connections between separate disciplines related to environmental health. My experience as both an environmental consultant and an academic researcher gives me the necessary knowledge and experience to apply research-derived results to real world applications. Since 2005, I have been part of the NIEHS Superfund Research Program community. Currently I serve as the co-leader of the Research Translation Core (RTC) and the Community Engagement Core (CEC) at the University of Kentucky Superfund Research Center (UKSRC). My research program is focused on stakeholderrelevant, solution-oriented research related to environmental fate and transport, with recent emphasis on the issue of vapor intrusion. In addition, my experience as a governmental liaison ( ), as well as my role in the RTC and CEC at UKSRC, provides countless contacts with community stakeholder, regulators and environmental practitioners with whom I consult regularly to ensure my research is relevant and meaningful to stakeholders. In this project, I will lead our research team s efforts related to Specific Aim 3 (Incorporate models into flux measurements to improve characterization of exposure risks) and Specific Aim 4 (Evaluate relevant research findings for policy decision makers) and will collaborate with our team on Specific Aims 1 and 2 (flux meter development). I have published nearly 30 peer-reviewed journal articles, presented at over 50 conferences, collaborated with individuals at 11 different academic universities, and has raised over $1.7 million dollars in research funding. My research has been cited by USEPA, CDC/ATSDR and several state agencies. Below are four publications that demonstrate my expertise related to the project s Specific Aims. 1.

Contribution to Science 1. Numerical Modeling: The Johnson & Ettinger (J&E) model, which is a 1D model, is by far the most widely used vapor intrusion model due to its adoption by the United States Environmental Protection Agency (USEPA). USEPA supports the use of vapor intrusion models as one of many lines of evidence during vapor intrusion site characterization efforts. Because of limitations of a 1D model, governmental agencies approached me to explore whether a more sophisticated 3D model might improve estimates of vapor intrusion exposure risks. In response to this request, we developed a finite element computation fluid dynamics (CFD) 3D model that could be used to investigate issues that were of interest to governmental agencies. Pennell et al and Bozkurt et al represent the first vapor intrusion articles to be published by our group and describe the model we developed. Since that time, we have expanded our model to include the effects of rainfall events, preferential pathways and heterogeneous soil types. To date, we have published approximately 20 articles related to vapor intrusion, including the four cited below that

3 describe some of our numerical modeling efforts. As discussed in my Contribution 2, we have also published an article that calibrated our model using field data, which is the first published attempt to calibrate a 3D vapor intrusion model using field data collected at a vapor intrusion site. My NSF CAREER award (Vapor Intrusion, Knowledge Brokers and Environmental Health: A Three Dimensional Perspective, ) will continue to expand this research to make scientific discoveries related to indoor air quality and the role of air transport into and around buildings. a.

Journal of the Air & Waste Management Association, 65(2): PMID: Research Translation for Vapor Intrusion: A knowledge broker is an intermediary who considers the range of opportunities available for scientific experts to engage with so that research findings have meaning and relevance for stakeholders. Being involved in research translation and community engagement activates for over a decade has allowed me to develop a unique perspective to consider vapor intrusion-related research in the context of regulatory policy systems and to serve as a knowledge broker, translating research for a policy decision makers. As an example of my contribution to this area, below are three key articles that summarize research that I led. Pennell et al (2013a) describes how knowledge brokers can serve important roles to ensure regulatory policy processes are connected with research findings. This article was recently cited by Anderson et al. (2015) in a premier environmental health journal (Environmental Health Perspectives) as part of an argument that knowledge-interweaving skills are critical for the next generation of scientists and engineers to address environmental health burdens. The other two articles cited below (Pennell et al. 2013b, and Pennell et al. 2016) summarize field investigations that I led in close collaboration with regulatory agencies. Pennell et al. (2013b) establishes a new exposure pathway that had not been previously identified by regulatory agencies (the sewer-gas-to-indoor air vapor intrusion pathway). This article has been cited in governmental documents by the USEPA, CDC/ATSDR and several state agencies. Pennell et al. (2016) summarizes the results of a field study that was conducted in collaboration with the Massachusetts Department of Environmental Protection. All three of these articles are significant because they include co-authors who have formal training in considerably different backgrounds engineering, public health, sociology, and exposure biology and provide evidence of my abilities to successfully direct multi-disciplinary research projects and to influence policy decision makers through research translation. a.

Field Data and Numerical Modeling: A Multiple Lines of Evidence Approach for Assessing Vapor Intrusion Exposure Risks Science of the Total Environment, 556: PMID: Fate and transport of non-volatile chemicals (e.g. nanosilver and persistent organic pollutants): Environmental toxicity is a key area of concern for high-volume nano-silver (nag) production and use is the natural environment. Much of the data on silver toxicity predates the nano-manufacturing era and thus relates to ionic Ag and its complexes rather than to nag directly. My research in this area aims to better understand the forms of silver that exists in various environmental systems where nag is present. With researchers from Brown University (Liu et al., 2011), we established sulifidation kinetics and evaluated various environmental systems that might be important for fate and transport considerations of nag. I have also collaborated with the USEPA research labs to investigate sampling methodologies for persistent organic pollutants. We investigated passive sampling techniques in the Narragansett Bay and continue to evaluate these methods within regulatory context for characterizing human and ecological health risks associated with contaminated sediments. a.
