His current research interests involve the development of survey data collection and analysis methods, including the design of telephone samples for households in the U.S.; the behavior of analytic statistics when data are obtained from complex sample surveys; imputation methods to compensate for item missing data in surveys; weighting to compensate for unit nonresponse; and the interaction between interviewer and respondent in the survey interview.
