Charles Aquadro

I am a research scientist and educator. I view these responsibilities part of a continuum that runs from current students to alumni to the general public. My research is focused on discovering basic principles that determine the amount of diversity that exists within and between the genomes of organisms, and how we can use that diversity to understand organismal diversity, to discover novel genes, to maximize human health, and to advance agriculture. Our research is carried out primarily with Drosophila, though past work has included mammals and plants. Our current research aims to evaluate the evolutionary flexibility of the genes that regulate germline stem cell maintenance and differentiation using combined population and functional genomic approaches. My teaching covers the concepts and methodologies of population genetics and comparative genomics, and personal genomics and medicine.

I currently teach a large undergraduate class in personal genomics and medicine (BioMG1290). I had previously taught the core Population Genetics course at Cornell since 1986. I also have given explorations for introductory biology students, alumni and public lectures on the genetics of diversity and genomics, and served as scientific advisor to science television (NOVA, WGBH, Discovery Channel).
