Research Statement
Dr. Bilker's methodological research interests are in the areas of pharmacoepidemiology, survival analysis, psychiatric methods, and correlated data. His primary applied research interests are in schizophrenia and the analysis of pharmacoepidemiology data using large databases. He is the principal investigator of the biostatistics and data core of the Schizophrenia Center in the Department of Psychiatry, which has an emphasis on the study of the relationship between brain imaging findings and the clinical course of schizophrenia.
