Don Jang is Vice President and Director of the Center for Excellence in Survey Research and serves as its Director. He is responsible for overseeing all staff and operations in the CESR department; building and leading the survey analytics team to help transform data collections to meet the demands of information with respect to timeliness, quantity, and quality; and building and leading data analytics team to bring advanced analytics to all NORC project offerings.
Jang has over twenty years experience managing and directing large-scale national federal statistical projects and methodological research associated with federal statistics programs. He has broad experience across all aspects of statistics, including multivariate statistical modeling, data linkage of multiple survey and administrative data, statistical disclosure avoidance, adaptive survey design, real time survey data processing, sampling, estimation, and report and data file production.
Before joining NORC in 2016, Jang was director of Data Science and Statistics of Mathematica Policy Research, building and growing the group to have more than 50 statisticians and data scientists. Jang's longtime commitment to supporting national Science Foundation's NCSES programs has been dated back to his tenure at Mathematica. Jang had led all statistical tasks for the Scientists and Engineers Statistical Data System (SESTAT) project since 1996. The SESTAT database integrates data collected through three national sample surveys supported by the National Science Foundation (NSF): the National Survey of College Graduates (NSCG), the Survey of Doctorate Recipients (SDR), and the National Survey of Recent College Graduates (NSRCG). For that project, Jang has led all activities needed for statistical support of the SESTAT system, including linking multiple survey data; optimum sample allocation to meet a number of statistical precision goals; dynamic, streamlined, real time data processing for data editing, imputation, and model-based weighting production for large scale data collection, developing SESTAT variance estimation methodologies, constructing longitudinal weights for longitudinal data analysis, and providing general statistical consultations to NSF and data collection contractors.
Jang had been a member of the Statistical Evaluation Committee for the NSCG since its 2010 redesign based on American Community Survey (ACS) data for its sampling frame. As a committee member, Jang provided statistical advice to the NSF and Census Bureau NSCG statistical staff.
Jang previously taught graduate and undergraduate courses at George Washington University and George Mason University. He is currently a board member of the Korean International Statistical Society and also a board member of Hope Nicaragua; he has served as an at large board member and methodology program and section chairs for the Washington Statistical Society.
