Dr. Eun Sug Park is a Senior Research Scientist at TTI. Dr. Park has extensive experience in 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, uncertainty estimation, high dimensional data analysis, environmental modeling, source apportionment/identification, and assessment of health effects associated with multiple pollutants.
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 evaluation of various countermeasures by using Bayesian methods, development of a multivariate approach for jointly modeling crash counts by severity data using Markov chain Monte Carlo (MCMC) methods, quality control of large transportation databases, sensitivity analysis of the pavement performance prediction program, and developing an innovative Bayesian approach for pavement performance prediction. She has also developed various experimental designs in a broad range of application areas including before-and-after field experimental designs to evaluate motorist response to innovative Traffic Control Devices, D-optimal experimental designs to identify important factors affecting the performance of asphalt pavements, and experimental designs for assessing the accuracy of test procedures. Dr. Park has led air pollution research projects for developing enhanced statistical methods for assessing health effects of multiple air pollutants for the Health Effects Institute and for estimating traffic-related air pollution for the Center for International Intelligent Transportation Research. She is currently developing Bayesian hierarchical models accounting for exposure measurement errors to estimate associations between ambient pollutants and cognitive decline for the NIH-funded study.
Dr. Park has authored or co-authored over 130 refereed journal papers or 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 (AED60) Committee, and Editor for Statistics of the journal Chemometrics and Intelligent Laboratory Systems.
