Biostatistics and Epidemiology
Faculty and Staff
Xi Kathy Zhou, Ph.D., M.S., joined the faculty at Weill Cornell Medical College from the Genomic Institute of Novartis Research Foundation in San Diego, where she served as a biostatistician and worked on projects related to microarray and high-throughput screening data analysis. She holds a Ph.D. from the Institute of Statistics and Decision Sciences at Duke University. She has extensive knowledge of Bayesian statistical methods and hierarchical models and is highly experienced in handling large complex datasets and proficient in statistical programming for complex statistical models. She developed a novel Bayesian hierarchical classification model to classify missense mutations of disease genes, made theoretical contributions to devise formulas for power and sample size calculation of strata-matched non-randomized studies with survival outcomes, and contributed greatly to the development of statistical methods and software for estimating minimum inhibitory concentrations based on microbial growth curves. She has been collaborating extensively with researchers at WCMC with a focus on multilevel modeling and statistical methods for cancer related laboratory researches. She has 19 publications. Her current projects include developing statistical methods for improved assessment of molecular signatures using microarrays (funded by CTSC at WCMC) and developing comprehensive prognostic models for esophageal cancer using Bayesian approaches (expected to be funded by NIH/NCI). She also mentors graduate students with design of their experiments and data analysis and teaches in the biostatistics course for the graduate school.
