The Amgen Foundation has a wonderful program that provides hundreds of undergraduates the chance to do summer research at one of ten leading research universities in the United States. Each host institution has its own application process. You can apply to participate at as many host institutions as you are interested in. To apply you must be a US citizen or permanent resident, a college sophomore or junior, have a GPA of 3.2 or higher, and be interested in a Ph.D. or M.D./Ph.D. in science. Application processes vary with campus, but most are due in early-mid February 2019. For more information, please check out the Amgen web site.
