Park, Eun TTI Senior Research Scientist


Dr. Park has over 24 years of experience in conducting advanced research on environmental concerns and transportation-related statistics issues. Her expertise includes environmental modeling and assessment of health effects of multiple air pollutants, modeling and analysis of transportation data, high-dimensional data analysis, latent variable models and factor analysis, spatial-temporal modeling and analysis, Bayesian hierarchical modeling, Bayesian model selection, and uncertainty assessment.

Dr. Park has led air pollution research projects for developing enhanced statistical methods for assessing health effects of multiple air pollutants and for estimating traffic-related air pollution. She is currently serving as multi-PI on a four-year, $2.16 million study funded by the National Institutes of Health (NIH) to evaluate the impact of source-specific multi-pollutant exposures and the neighborhood context on disparities in stillbirth. She is also developing Bayesian hierarchical models accounting for exposure measurement errors to estimate associations between ambient pollutants and cognitive decline for another NIH-funded study, as well as serving as PI on a project sponsored by Seoul National University for predicting unobserved source contributions for PM2.5 in South Korea.

Dr. Park has been leading modeling and data analysis tasks in numerous transportation research studies for Federal Highway Administration (FHWA), National Cooperative Highway Research Program (NCHRP), Texas Department of Transportation (TxDOT), Transit Cooperative Research Program (TCRP), and Bureau of Transportation Statistics (BTS). She is currently serving as Co-PI on an FHWA project for developing crash modification factors along with uncertainty estimates for pedestrians, left turn lanes, curves, and roadway departure safety improvements.

Dr. Park has authored or co-authored over 150 refereed journal papers and technical reports as well as a transportation statistics textbook titled 'Transportation Statistics and Microsimulation.' She was the recipient of the Transportation Research Board (TRB) Pedestrian Committee Outstanding Paper awards in 2006 and in 2009, the TTI/Trinity Researcher Award in 2010, and is the winner of the 2010 Patricia F. Waller Award (TRB), the 2011 D. Grant Mickle Award (TRB), the 2019 TRB Paratransit Committee Best Paper Award, and the 2021 TRB Safety Methods Committee Best Paper Award. Dr. Park is a Fellow of the American Statistical Association (ASA), an Elected Member of the International Statistical Institute (ISI), a Member of the TRB Statistical Methods Committee, and Editor for Statistics of the journal Chemometrics and Intelligent Laboratory Systems.
