Description of Research Expertise

Research interests: Research in the Gao lab aims to address questions in human genetics in an evolutionary context by computational approaches.

Keywords: population genetics, natural selection, mutation, human disease, complex traits

Research details: One theme of our research is the genesis and accumulation of mutations in natural populations. We are particularly interested in the mechanisms and timing of mutagenesis in the germline and somatic tissues as well as the causes and consequences of mutation rate variation. To answer these questions, we take a computational approach to integrate data from comparative genomics, human genetics, cancer genetics and developmental biology. Another research direction in the lab is to understand the genetic basis and evolution of human phenotypes. We have developed methods to detect and quantify impacts of natural selection under diverse evolutionary scenarios, including purifying selection on severe Mendelian disease mutations, balancing selection in maintaining ancient polymorphism, and stabilizing selection on gene expression. A primary aim of our current research is to understand the genetic architecture and evolution of complex traits in human populations by mathematical modeling and statistical analysis of genomic data from modern and ancient samples.
