Research & Interests

Broadly speaking, my research interests focus on incomplete-data problems. Some of my efforts involve problems where data are incomplete due to nonresponse (e.g., subjects failing to answer survey questions, as in 3 or due to design decisions (e.g., an investigator intentionally obtained measurements on some but not all subjects on a given variable, as in 4. My work also includes studying models (hierarchical models, mixture models) where adopting a view that certain quantities are unobserved motivates a solution to an estimation problem, and ongoing work (starting with 13 and 6 addresses incomplete data in longitudinal studies. I hold a joint appointment in the Department of Psychiatry and Biobehavioral Sciences in the UCLA School of Medicine, and in recent years, mental health research has been a major area of application (8;11;10). I have developed mixture-modeling methods for performing linkage of multivariate records (2; 9), and this work served as motivation for a recent proposed methodology for DNA identification (5). I also have maintained an interest in methods for addressing the census undercount problem following on earlier work at the U.S. Census Bureau (3; 12; 7) and in reporting of polling margins of error (1).
