Promod K. Chandhok is an American mathematical statistician whose work includes survey methodology, transportation statistics, and the integration of auxiliary and administrative data in federal surveys. He served as a Senior Mathematical Statistician at the United States Census Bureau and the Bureau of Transportation Statistics (BTS), and is the co-author of Sample Survey Theory, which has been widely used as a graduate-level text in survey sampling in the United States, India, and internationally.[1][2][3] Chandhok is an Elected Member of the International Statistical Institute.
Chandhok's career includes academic appointments, federal statistical research, and leadership roles in professional organizations. He taught quantitative methods at Ohio University and survey sampling at The George Washington University, conducted methodological research for the Current Population Survey at the Census Bureau, and later contributed to major federal transportation surveys at BTS. He was the founding organizer of the American Statistical Association's Transportation Statistics Interest Group (TSIG) and served as Project Director of the BTS Grant Program for Research and Development in Transportation Statistics.
His research contributions include early applied demonstrations of response propensity modeling, work on measurement error and interviewer effects, and methodological developments for the Commodity Flow Survey and National Household Travel Survey. Chandhok's applied work put into practice theoretical developments by Little, Bethlehem, and others.
Chandhok is an Elected Member of the International Statistical Institute and received the Washington Statistical Society President's Award in 2016 for long-term professional service. He has also been active in editorial review, grant management, and professional activities within the federal statistical system and the American Statistical Association.
Education
Chandhok completed his BA in statistics, mathematics, and economics and earned an MA in mathematical statistics from the University of Lucknow. He later received an MS and Ph.D. in statistics from Iowa State University. His dissertation, supervised by Chien-Pai Han, was titled A study of the effects of measurement error in survey sampling.[4][5]
Career
Chandhok began his academic career as an Assistant Professor of Quantitative Methods at Ohio University in Athens, Ohio, where he taught a range of quantitative methods courses from 1982 to 1989. He later joined the Statistical Research Division of the United States Census Bureau as a Mathematical Statistician, conducting methodological research for the Current Population Survey (CPS). His work included one of the earliest applied demonstrations of response propensity modeling using logistic regression.[6]
He subsequently served as a Senior Mathematical Statistician at the Bureau of Transportation Statistics, where he contributed to the design and evaluation of major federal transportation surveys. His work supported the redesign of the Commodity Flow Survey[7] and methodological improvements to the National Household Travel Survey.[8][9][10][11]
Chandhok also held long-term teaching appointments at The George Washington University, where he taught graduate-level survey sampling theory and variance estimation and served on doctoral committees.[12][13][14] His book Sample Survey Theory has been widely used as a graduate-level text in survey sampling in the United States, India, and internationally.[15][16]

Research contributions
Chandhok's research includes survey sampling theory, measurement error models, and the use of auxiliary information in federal surveys.[22] His early work at the Census Bureau included the earliest applied demonstration of response propensity modeling using logistic regression.[6] The concept of response propensity was introduced by Little (1986)[23] and refined by Bethlehem (1988).[24] Chandhok's applied work put into practice these ideas within federal survey organizations, bridging theoretical developments of the 1980s with later syntheses by Groves and Couper (1998).[25] Subsequent research extended these ideas into responsive and adaptive survey designs.[26]
Awards and Honors
Chandhok is an Elected Member of the International Statistical Institute[27]
He received the Washington Statistical Society President's Award in 2016 for "long-term dedicated efforts as head science fair judge."[28]

He served as Chair of the Washington Statistical Society's Social and Demographic Statistics Program from 2007 to 2018, jointly with J. Druittcour until 2017.[29]
Editorial Review and Grant Management
Chandhok served as Project Director of the BTS "Grant Program for Research and Development in the Field of Transportation Statistics," where he reviewed proposals and chaired grant review panels.[30][31][32]
He also served as a reviewer for the Journal of Transportation and Statistics.[33]
