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.
