John Klein,PhD is an expert in statistical methods for longitudinal data. He has published extensively on statistical methods for survival data and on the use of these techniques in analyzing complex illness-death models. His areas of research include the use of graphical association models for longitudinal studies, stochastic modeling of disease processes and the design and analysis of clinical trials. Dr. Klein is the Head of the Division of Biostatistics and Statistical Director of the International Bone Marrow Transplant Registry. He was formerly the Statistical Director of the Ohio State University Comprehensive Cancer Center. He serves on the editorial board of Lifetime Data Analysis and Biometrics . He is an elected member of the International Statistics Institute .

Raymond Hoffmann, PhD is an expert in time series analysis, statistical methods for epidemiology and analysis of variance involving repeated measures. He has extensive experience with the design and planning of community studies. Dr. Hoffmann is the Biostatistician for the Clinical Research Center. He has been the president of the local chapter of the American Statistical Association. He is certified by the American College of Epidemiology and is Publications Officer of the Statistics in Epidemiology Section of the American Statistical Association.

Prakash Laud, PhD is an expert in Bayesian analysis and decision theory. He has wide-ranging interests in linear and generalized linear models as well as in modern parametric and nonparametric Bayesian methods. He serves on the editorial board of the Journal of Nonparametric Statistics, and is the Director of the Statistical Core of the Model Spinal Cord Injury Center at MCW/FMLH.

Brent Logan, PhD has research expertise in multiple comparison procedures and methods for analyzing multiple endpoints in clinical trials. He serves as a Biostatistician for the clinical trials network of the International Bone Marrow Transplant Registry. He has research interests in multiple comparison procedures, clinical trial design, analysis of neuroimaging data, methods for analyzing multiple endpoints in clinical trials, and inference in dose-response studies.

Daniel Rowe, PhD holds a primary appointment as an assistant professor of Biophysics in the Biophysics Research Institute and comes to the Medical College of Wisconsin after being a postdoctoral scholar at Caltech researching and developing in the area of functional magnetic resonance imaging. Professor Rowe also has research interests in Bayesian factor analysis and latent variables. These are multivariate psychometric techniques that describe unobservable underlying relationships which are present in observable random variables.

Aniko Szabo, PhD , Associate Professor, is the Consulting Service Director. Prior to coming to MCW she was Biostatistics Resource Director at the University of Utah Huntsman Cancer Institute.

Sergey Tarima, PhD - Professor Tarima is the assistant-director of the Biostatistics Consulting Center. His current research interest include methods on using additional information in statistical estimation, estimation on missing, censored and partially grouped data, and survey data analysis.

Tao Wang, PhD Professor Wang's diverse research interests include statistical genetics, time series analysis, neural networks and dynamical systems modeling and analysis. Currently his research is focused on linkage disequilibrium mapping of quantitative trait loci (QTL) using polymorphic genetic markers, and developing methods for statistical genetics. He also holds a joint appointment at the Human Molecular Genetic Center (HMGC).

Mei-Jie Zhang, PhD  has extensive experience in analyzing complex survival data. He has wide-ranging interests in inference for counting processes, time series analysis and statistical consulting. Professor Zhang is the Biostatistician of the International Bone Marrow Transplant Registry.
