Research in the Ramachandran lab addresses problems in population genetics and evolutionary theory, generally using humans as a study system. Our work uses mathematical modeling, applied statistical methods, and computer simulations to make inferences from genetic data. We ask a range of questions, such as: what features of human demographic history can we infer from genetic data alone? how can we detect genomic targets of selection? how is human genetic variation apportioned across chromosomes, and what does this teach us about past evolutionary processes shaping genetic variation? how does population genetics research highlight our shared humanity?
Our research and a subset of lab members are currently funded by multiple grants from the National Institutes of Health.
