The Doctor of Philosophy (PhD) degree is intended primarily for students who desire a career in research, advanced development or teaching. PhD programs are designed to give students a broad background in mathematics and engineering sciences, together with intensive study and research experience in a specialized area.
Current Stanford MS students interested in adding a PhD program to their academic career should speak with the staff at the Aero/Astro Student Services Office about the necessary paperwork and relevant policies. If you are a current master's student in the Stanford Aeronautics and Astronautics Department, to apply for the PhD, you must complete paperwork prior to conferring the MS degree. Failure to do so will require an application through the online admissions process along with all other external applicants.
A majority of PhD students at the Aeronautics and Astronautics Department completed the Stanford MS program. A small number of students who acquired a master's degree from other institutions are admitted each year. We highly recommend that undergraduate students interested in a PhD from Stanford Aeronautics and Astronautics apply for the Stanford MS program first. The PhD program only admits students who already hold (or are currently studying for) an MS degree. If you are applying from another institution, your MS degree must be conferred prior to starting the PhD.
Those wishing an Engineer's Degree or PhD who do not have a master's degree should apply for the master's degree and indicate on the application their desire to continue their studies beyond that degree.
