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 their 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 their advisor is a senior member at the ITC.
