Short Biography

Dr. Eun Sug Park is a Senior Research Scientist at Texas A&M Transportation Institute. Dr. Park has more than 24 years of experience conducting advanced research on transportation-related statistics issues, environmental concerns, and air pollution epidemiology, and has collaborated with transportation/environmental engineers, epidemiologists, and scientists in other fields. Her expertise includes modeling and analysis of transportation data, safety analysis, environmental modeling, source apportionment, health effects evaluation, high-dimensional multivariate data analysis, latent variable models and factor analysis, Bayesian hierarchical modeling, spatial-temporal modeling, and uncertainty assessment.

Since joining TTI in 2001, Dr. Park has been leading modeling and data analysis tasks in many transportation research studies for FHWA, NCHRP, TxDOT, TCRP/NCHRP, and BTS. Some of those advanced data analysis efforts included safety evaluations of various countermeasures employing Bayesian and frequentist methods, developing a multivariate approach for jointly modeling crash counts by severity data, quality control of large transportation databases, and developing an innovative Bayesian approach for pavement performance prediction. 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 led air pollution research projects for Health Effects Institute for developing enhanced statistical methods for assessing health effects associated with multiple air pollutants and for the Center for International Intelligent Transportation Research 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 authored or co-authored over 150 publications including a transportation statistics textbook titled ‘Transportation Statistics and Microsimulation’. She was the recipient of the TRB Pedestrian Committee Outstanding Paper awards in 2006 and 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.
