Former Grad Students

At Columbia over the last twenty years, the median time to degree has been 6 years, with a range of 4 to 8; only three students have taken seven years or more. There is, however, no strict time limit — the only criterion for continued support is that the student be making satisfactory progress toward the degree.

Since their inception over 30 years ago years, 17 of our graduates have won Hubble, Einstein, and Sagan Fellowships and three have won Jansky Fellowships; two have won the annual Trumpler Award for the Outstanding Dissertation by a Student in North America. Others have gone on to postdoctoral fellowships at institutions such as Berkeley, Harvard, Princeton, Caltech, SAO, Washington, and Munich. Twenty-eight now hold faculty positions. Over the past decade 58% of our PhDs were awarded to women.
