 Overview
Xin Tu (Ph.D.) is Professor of Biostatistics and Psychiatry in the Department of Biostatistics and Computational Biology and Department of Psychiatry. He is the Director of the Statistical Consulting Center and the Director of the Psychiatric Statistics Division within the Department of Biostatistics and Computational Biology.
Dr. Tu has done important work in the areas of U-statistics, longitudinal data analysis, survival analysis with interval censoring and truncation, and pooled testing, and has successfully applied his novel development to addressing important methodological problems in HIV/AIDS, mental health and psychosocial research. In recent years, he and his group have been focusing on issues arising in research on accuracy of proxy outcomes, causal effect from group-based psychosocial interventions and observational longitudinal data, and intervention pathways (mechanism of action) as well as interplay between biological, behavioral and societal factors in the study of disease etiology and treatment.
Dr. Tu has co-authored a book entitled: Modern Applied U-Statistics, six book chapters, over ninety peer-reviewed publications and numerous conference abstracts. He has mentored two Ph.D., one postdoctoral and numerous Master-level students in biostatistics. The Ph.D. and postdoctoral students all have successfully secured faculty positions at major research universities including the Johns Hopkins University. He is currently mentoring two post-doctoral and three pre-doctoral students.
