Dr. Quefeng Li is an assistant professor in the Department of Biostatistics. He earned his doctoral degree in statistics in 2013 from University of Wisconsin, Madison.

Dr. Li’s research is focused on developing new statistical tools for analyzing complex data that arose in biomedical science studies. He has developed new methodology for the classification, variable selection and robust estimation of high dimensional data. He has also worked on the development of new data integration tools, which target to extract key information from multiple datasets and improve the reproducibility of science studies. Such tools are applicable for synthetic analysis of datasets from popular data consortia, such as GEO and TCGA.
