Translational Statistics:  We work at the crossroads of statistical science and contemporary medical and biological research.  Our goal is to advance medical knowledge by engaging as full intellectual partners with colleagues in Psychiatry, Pediatrics and elsewhere to provide integrated, statistical solutions to research-generated problems. 

 

An important element of our work is the invention and implementation of new statistical methodology, using high-level computational skills to translate fundamental concepts, models and principles of statistics into unique scientific contexts.  We are especially interested in statistical genetics and genomics (including family data); multiple hypothesis testing and simultaneous inference in complex settings; and problems that require non-standard statistical models.  A notable example can be found in the seminal paper (below) introducing the Plaid model for identifying two-way "bi-clusters" in gene expression data.  In recent work, we have addressed the implications of ever-increasing numbers of hypothesis tests in high-throughput biology and have developed a new, efficient and flexible, statistical framework for analyzing twin data.
