Hongshik Ahn

Professor, Ph.D., 1992, University of Wisconsin
Biostatistics; Survival Analysis

Hongshik Ahn’s specialty is tree-structured regression modeling for censored survival data.  After earning his Ph.D., he initially worked as a biostatistician at the National Center for Toxicological Research (NCTR) on animal carcinogenicity, developmental toxicology, and drug stability analysis. He came to Stony Brook in 1996, but continued working on NCTR problems while developing new collaborations with Stony Brook biomedical researchers.  His research has been funded by NIH.

Professor, Ph.D., 1973
Princeton University: Applied Statistics

Stephen Finch is an applied statistician whose major areas of interest are statistical genetic epidemiology and applied longitudinal data analysis. Statistical genetic epidemiology studies the genetics of complex human traits, such as bipolar disorder or schizophrenia. One of the major longitudinal studies, with faculty in the Stony Brook Department of Psychiatry, concerns the effects of medications on the course of mental illnesses.

Associate Professor, Ph.D., 2008
University of Florida: Statistics

Song Wu’s research focuses mainly on statistical genetics by developing new methodologies to unravel the genetics underlying complex traits. He had received intensive training in both Statistics and Genetics, and is working towards bridging these two fields. His specific research areas include QTL mapping, linkage mapping, linkage disequilibrium mapping, microarray data analysis, genome-wide association study, next-generation sequencing data analysis (WG-seq, RNA-seq, ChIP-seq), molecular pathway analysis, bioinformatics and applied longitudinal data analysis.

Deputy Chair, Professor, Ph.D., 1996
University of California, Los Angeles: Biostatistics

Wei Zhu is a statistician whose diverse research projects include design and analysis of experiments (for dose response studies and clinical trials), longitudinal and contemporaneous pathway discovery and analysis (for biological pathways and financial networks), errors in variable modeling (for measurement platform/instrument comparisons and calibrations), and robust regression analysis. Her former students have taken positions in academia and in a broad range of industry as quality control managers, biostatisticians, risk managers and financial analysts. Professor Zhu is also affiliated with the SBU Center for Finance ( t
