Min Zhang, PhD
- Professor, Biostatistics
Min Zhang's statistical methodological research has been focused on semiparametric methods, causal inference (comparative effectiveness analysis), dynamic treatment regimes/statistical learning method for optimal treatment decision making (individualized medicine), survival data analysis/competing risk analysis, missing data and clinical trials. She is interested in using semiparametric methods/theory to develop more robust and efficient methods for analyzing data obtained from clinical trials and observational studies (e.g., clinical registries, health claims data). For example, she develops doubly robust and propensity score-based methods for accounting for confounders robustly in order to make causal inferences from observational studies. Another main research area is to develop statistical learning method for estimating the optimal treatment decision rule, which aims to find the optimal treatment option for each individual patient based on his/her own characteristics as opposed to the treatment with the best average treatment effect. In her methodological and collaborative research, she works on various types of data including, for example, survival outcomes, longitudinal, clustered and hierarchical data.
Dr. Zhang has been collaborating with researchers at Duke Clinical Research Institute (DCRI), UM Kidney Epidemiology and Cost Center (KECC), the Statistical Analysis of Biomedical and Educational Research Group (SABER) at UM, the UM School of Nursing, the Cardiovascular Center (CVC) and the Department of Cardiac Surgery at UM on various projects in many disease areas (e.g., cancer, end-stage renal disease, solid organ transplantation, cardiovascular diseases). She has served as a co-investigator on many NIH and AHRQ funded research projects. Currently, her collaborative research is mainly on cardiovascular diseases/cardiac surgery, and solid organ transplantation. Her research in cardiovascular disease focuses on understanding the variation in health care practices, quality improvement, and evaluating the effect and impact of clinical practices and patient characteristics in terms of clinical outcomes and health cost. Much of her research relies on national or statewide clinical registries (e.g., the Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative, the Interagency Registry for Mechanically Assisted Circulatory Support) and health claims data (e.g., Medicare claims data and Blue Cross and Blue Shield claims data). She also serves as the statistical editor of the Journal of Heart and Lung Transplantation.
