I develop methods for the analysis of multi-faceted high-dimensional data. These methods are usually motivated by applications in molecular biology, especially in "omics" fields such as genomics, metabolomics, and proteomics. My focus is in the integrated analysis of data that are from multiple sources (e.g., gene expression, metabolomics, imaging) or measured in multiple dimensions (e.g., multiple tissue types or body regions), which are often necessary to capture every facet of a complex biological system. I also have in interest in exploratory factorization and clustering methods, and Bayesian nonparametric inference.
