Professional Interests
My research focuses on the development of bioinformatics and biostatistics methods for analyzing high-dimensional genomic data. Areas of statistical interest include dimensionality reduction (e.g., PCA), hypothesis aggregation (e.g., gene set testing), and penalized estimation (e.g., LASSO penalized regression). Areas of biological interest include cell signaling, tissue-specific gene activity, tumor immunology, and cancer prognosis prediction.

Randomized Spatial PCA (RASP): a computationally efficient method for dimensionality reduction of high-resolution spatial transcriptomics data. Streptococcus pyogenes pharyngitis elicits diverse antibody responses to key vaccine antigens influenced by the imprint of past infections. Leveraging cell type-specificity for gene set analysis of single cell transcriptomics. CAraCAl: CAMML with the integration of chromatin accessibility. A highly sensitive 3base™ assay for detecting Streptococcus pyogenes in saliva during controlled human pharyngitis. A generalized eigenvector centrality for multilayer networks with inter-layer constraints on adjacent node importance. Identifying tumor type and cell type-specific gene expression alterations in pediatric central nervous system tumors. Reconstruction Set Test (RESET): A computationally efficient method for single sample gene set testing based on randomized reduced rank reconstruction error. Tissue-adjusted pathway analysis of cancer (TPAC): A novel approach for quantifying tumor-specific gene set dysregulation relative to normal tissue.
