Students may enter the Ph.D. program after successfully completing an M.S. degree program, at the University of Delaware or elsewhere, or may be admitted directly to the Ph.D. program directly after a Bachelors degree. To obtain a Ph.D., students will normally follow the course intensive regular track. Students entering the program with an M.S. degree in Physics or Astronomy that are particularly well prepared may choose to follow the less coursework intensive fast track.
