Institute of Statistical Science
I am currently an associate research fellow at the Institute of Statistical Science of Academia Sinica. My research interests focus on two areas in computational biology: 1)cancer genomics, 2)molecular evolution. In cancer genomics, we examined the combinatorial patterns of somatic mutations in cancer and related them to pathway and functional implications (FASEB J. 2008). We also developed a statistical model and inference algorithms to integrate multiple types of molecular aberration data (BMC Bioinformatics 2010) and applied them to large-scale cancer genomic data analysis (BMC Systems Biology 2011, Nucleic Acids Res. 2013). In addition to data analysis, we also proposed optimization algorithms for combinatorial treatments for a heterogeneous tumor population (PNAS 2012). In molecular evolution, we built a computational model that identifies coevolving nucleic or amino acids from aligned sequences of multiple species (Mol. Biol. Evol. 2007; PLoS Comp. Biol. 2007). We also proposed an algorithm that reconstructs the evolutionary history of biomolecular networks according to parsimony (Genome. Biol. & Evol. 2012). Furthermore, we developed a model to quantify the strength of purifying selection of sequence motifs and applied this method to exhaustively identify functional 10-mers from mammalian promoters (Nucleic Acids Res. 2013).
