Short Biography

Dr. Eun Sug Park is a Research Scientist at TTI. She received her Ph.D. in Statistics at Texas A&M University in 1997. She also holds an M.S. in Statistics and a B.S. in Computer Science and Statistics from Seoul National University. Dr. Park was a Visiting Assistant Professor at Texas A&M University in 1998. She worked as a Research Associate at National Research Center for Statistics and the Environment at the University of Washington from 1999-2001.

Dr. Park has extensive experience in conducting advanced research on transportation-related statistics issues and environmental concerns. Her expertise includes modeling and analysis of transportation data, experimental designs, safety analysis, quality control of large transportation databases, development of models for air pollution data and uncertainty estimation, and assessment of health effects associated with air pollution. Since joining TTI in 2001, Dr. Park has been leading modeling and data analysis tasks in many transportation research studies for TxDOT, NCHRP, FHWA, TCRP/NCHRP, and BTS. Some of those recent advanced data analysis efforts included safety evaluation of various countermeasures by using Bayesian methods (both empirical Bayes and fully Bayesian methods), developing an innovative Bayesian approach for pavement performance prediction, analysis and development of asphalt quality assurance procedures, sensitivity analysis of the pavement performance prediction program, and development of a multivariate approach for jointly modeling crash counts by severity data using Markov chain Monte Carlo (MCMC) methods. She has also developed various experimental designs in a broad range of application areas including D-optimal experimental designs to identify important factors affecting the performance of asphalt pavements, before-and-after field experimental designs to evaluate motorist response to innovative TCDs, and experimental designs for assessing the accuracy of test procedures. Dr. Park is currently serving as the key statistician on the FHWA-sponsored research project for assessing the effect of wider pavement markings on safety. She is also working on several TxDOT-sponsored research projects for determining the effectiveness of the current Texas statewide nighttime and truck speed limits, evaluating safety effectiveness of modern TCDs, and characterizing exhaust emissions from heavy duty diesel vehicles. Dr. Park is currently leading the HEI project for developing innovative statistical methods to characterize air pollutant mixtures and assessing their health effects.

Dr. Park has numerous publications in internationally known scholarly journals in transportation, statistics, and environmental research. She was the recipient of the TRB Pedestrian Committee Outstanding Paper awards in 2006 and in 2009, and is the winner of the 2010 Patricia F. Waller Award (TRB). She also co-authored a transportation statistics textbook titled `Transportation Statistics and Microsimulation' published in October, 2010.
