, he turned to computational problems in comparative genomics. In Haussler's group, he developed several analysis methods based on phylogenetic hidden Markov models, including a widely used program called phastCons for identifying evolutionarily conserved sequences in genomic sequences. At Cornell, Siepel's research group continued to work on the identification and characterization of

, carried out in close collaboration with John T. Lis's laboratory. A common theme in Siepel's research is the development of precise mathematical models for the complex processes by which genomes evolve over time. His research group uses these models, together with techniques from computer science and statistics, both to peer into the past, and to address questions of practical importance for human health.
