The Eric R. Keto Prize for Graduate Students in Theoretical Astrophysics, endowed with a generous donation by ITC Senior Member Eric Keto, is awarded each year for the best thesis in theoretical astrophysics by a student at the CfA, as selected by the Senior Members of the ITC. The restriction is that the nominated student needs to receive her/his PhD in the year of the award on a topic in theoretical astrophysics. The student can be from any department within Harvard as long as her/his advisor is a senior member at the ITC.
