My research focuses primarily on the computational analysis of biological sequence data, particularly large-scale nucleotide sequence sets, such as the output of the latest DNA sequencers and the genome sequences that may be assembled with them. This area of research is crucial to the advancement of biology, which has become increasingly dependent on high-throughput sequencing for a wide variety of applications. My projects generally fall into one of two main lines of research: (i) transcriptome analysis with RNA sequencing (RNA-seq) data, and (ii) evolutionary analysis of whole genomes. In both lines of my research, I focus on the development of new computational methodology that is both efficient and statistically-grounded.
