Between 12 and 14 students enroll in this highly competitive program every year, and at any one time 25 or so are performing thesis research in Rockefeller University laboratories. Students spend their first two years in medical school, while also completing three research rotations. Following the completion of graduate studies and thesis research at either The Rockefeller University, the Gerstner Sloan-Kettering Graduate School of Biomedical Sciences or Weill Cornell Graduate School of Medical Sciences, students receive their Ph.D. degrees and then reenter medical school to complete clinical rotations and receive their M.D. degrees.
