For the past twelve years, Dr. Pekar has worked in EPA’s Office of Air Quality Planning and Standards (OAQPS) in Research Triangle Park, NC. While at OAQPS, he has played a lead role in designing and implementing human health risk assessments and regulatory impact analyses as part of regulatory review for criteria air pollutants including ozone, particular matter and lead. More recently, he participated in the risk assessment and regulatory impact analysis completed in support of efforts by EPA to regulate mercury emissions from power plants. Dr. Pekar’s work at EPA has involved application of cutting edge methods in probabilistic risk assessment, epidemiological-based population (incidence) risk modeling, multi-pathway exposure and risk assessment and economic valuation of health impacts. Dr. Pekar has played a central role in briefing EPA management (at all levels) with regard to risk and benefits analyses in the context of national-scale regulatory review and has also appeared frequently before the Science Advisory Board (SAB) to explain an at times defend the Agency’s risk assessments as part of ongoing peer review by the SAB. Prior to working at EPA, Dr. Pekar worked at Research Triangle Institute (RTI) where he designed and implemented multi-pathway risk assessments and worked on the design of multi-pathway risk modeling software. Dr. Pekar holds a PhD and MSPH in Environmental Management and Policy, both from the School of Public Health at the University of North Carolina in Chapel Hill.
