My research uses population genetics to refine known aspects of the landscape and anthropogenic effects on the genetics of the macaque populations in Southeast Asia. I attempt to accomplish this in a few ways. First, by using the gene for the protein salivary amylase as a metric by which to study the diets of the macaques in the context of the amount of provisioning to which they are subjected. Second, I use next-generation sequencing to analyze the diversity and function, particularly in carbohydrate digestion, of the microbes present in the oral environment. Third, I use biomarkers and single nucleotide polymorphisms (SNPs) in the macaque genome to evaluate the overall adaptation of the communities and populations available to us in Southeast Asia. Together, these approaches will potentially allow a more complete view of the diet of primates and how environmental elements affect the response that can be reflected by the genome.
