The Computational Biology Research Group develops new computational methods, efficient algorithms, and powerful software tools to help answer fundamental biological questions. We are especially interested in problems related to understanding the evolution of genes, genomes, and species. Some of our specific projects include:
- Inferring gene family and genome evolution through gene duplication, horizontal transfer, and loss.
- Understanding evolution at the sub-gene/domain level.
- Reconstructing highly accurate gene trees in both eukaryotes and prokaryotes for evolutionary and functional genomic studies.
- Inferring infectious disease transmission networks.
- Building whole-genome and multi-locus species phylogenies.
