Research Interests
I collaborate with St. Jude investigators in the areas of hematological malignancies, pharmaceutical sciences, molecular pathology, bioinformatics, and computational biology. I am interested in statistics methodological research in several areas with applications to biomedical sciences.
- Statistical inference methods in systems biology and genome-wide integrated analysis, with emphasis on applications to cancer genomics
- Validation inference in genome-wide studies
- Estimation and control of false discovery rates; assessment of statistical significance in massive multiple comparisons applied to biomedical research, such as genome-wide studies
- Analysis of high-dimensional and large data sets, data mining, dimension reduction and visualization, variable (feature) selection for cluster analysis, modeling, and classification
- Methodologies of multivariate analysis: nonparametric methods combining linear or nonlinear projections and function estimation
- Applications of percentiles (quantiles) in data analysis and modeling
- Methods of analyzing general distance (similarity) and non-dimensional data, visualization, cluster analysis, and multidimensional scaling.
