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 (29), 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 (3127) and in reporting of polling margins of error (1).
