Dr Wu's research focuses on developing statistical methods and softwares for high throughput technologies such as DNA microarrays, second generation sequencing and high throughput screening assays. Recent topics of methodological development include methods for differential expression and normalization in RNA sequencing data, cross platform data combination of microarray and NGS, social network models in gene set analysis. Recent collaborative work involves epigenetic variations in cancer samples, transcriptomic responses in toxicity studies, differential expression in diatom using NGS, identifying biomarkers from high throughput screening.

Zhijin (Jean) Wu's research interest is in statistical methodology for data from biological experiments, especially those generated from high-throughput biotechnologies.
We are developing methods for genomics in general, with a current focus on single cell gene expression (single cell RNAseq), and gene set/network analysis.
