Research Interests

I work on computational comparative genomics in the lab of Manolis Kellis. Specifically, I am developing methods for the analysis of protein-coding genes in alignments of multiple related genomes. The purpose of these methods is to use evolutionary signatures at the DNA sequence level to (1) validate and revise existing gene annotations; (2) identify novel genes and exons ab initio; and (3) discover unusual genic phenomena, such stop codon readthrough, translational frame-shifting, polycistronic mRNAs, and extremely small proteins.

We are applying these methods to the genomes of several fungal species (including baker's yeast, Saccharomyces cerevisiae, and a human pathogen, Candida albicans), the fruit fly Drosophila melanogaster, and the human, using genome alignments with several related informant species in each case - at last count, seventeen fungi, twelve flies, and twenty-two mammals. Ultimately, our efforts will help produce the best possible gene annotations for the ever-increasing collection of sequenced genomes.
