Dr. Sellers received his Ph.D. from the University of Pennsylvania in 1965 and completed his postdoc at the Johnson Foundation for Medical Research. He joined the faculty of Rockefeller University in 1966. He is currently the curator of the university's Merrill W. Chase Historic Scientific Instrument Collection. Dr. Sellers is a mathematician working in combinatorial analysis and theoretical computer science, fields that in the last few decades have undergone extraordinary advances that have converged with comparable breakthroughs in molecular biology. Dr. Sellers works in collaboration with members of other laboratories to tackle problems in molecular biology that can be stated in mathematical terms and solved computationally, including those related to DNA and protein databases.
