Research Interests

My interests as a statistician cover multivariate analysis and dimension reduction in regression context. In collaboration with R. Dennis Cook (Statistics, UMN), I do research on Sufficient Dimension Reduction (SDR). SDR is a body of theory and methods for handling high-dimensional regression and classification problems prior to the use of parametric models or non-parametric fits, and it is closely related to graphics and data visualization. Its popularity and application scope have increased steadily in the last decade, along with the availability of large-scale, high-dimensional data in many scientific fields. Our recent work concerns foundational aspects, SDR in multi-dimensional reponse regression with a mix of quantitative and categorical predictors, novel SDR techniques, and an ongoing attempt to extend SDR's theoretical framework and methodology to non-linear dimension reduction. Also, I am currently looking forward to applying these techniques to Genetics, Genomics, and Bioinformatics (e.g. gene expression data from microarrays).
