Essentially, all models are wrong, but some are useful.

Research Interests

My research interests lie in the broad areas of evolution. I am particularly interested in developing new computational and statistical methods to study the evolution of human and nonhuman primates. Currently, I am studying methods for more accurately genotyping copy number variation of duplicated genes and gene families within human and great ape genomes. The goal is to understand the origin and the evolution of duplicated genes as well as their roles in human diseases, such as intellectual disability.
