One of the great features of working in the OSU Astronomy Department is that we get lots of terrific students and postdocs, and we train them in an environment that encourages them to become wide-ranging and productive researchers.
(Apologies in advance for any out-of-date information on this page, as I revise it irregularly, most recently in February 2024. Feel free to send me corrections and updates.)
The students who have been my primary thesis advisees are:

He is now an Assistant Professor of Physics at the OSU Marion campus.
Vimal Simha, 2011

I have also been fortunate to work with a number of excellent postdocs at Ohio State, some of them supported by my grants, two by Hubble Fellowships, and others supported by other faculty or by OSU's Center for Cosmology and Astro-Particle Physics. While it is generally unambiguous who your thesis advisees are, the boundary for postdoctoral advisees is more fuzzy. Postdocs I have collaborated with and (I hope) mentored at Ohio State are, in chronological order:
now on the faculty at Carnegie Mellon University.
now the Dean of Physical Sciences at U.C. Irvine.
(Hubble Fellow), now on the faculty at University of Chicago.
now a Professor and leader of the Cosmic Dark Energy and Dark Matter research group at the National Astronomical Observatories of China, in Beijing.
now a faculty member at the University of Michigan.
now a faculty member in the Astronomy Group at the University of Southampton.
(CCAPP Fellow), now a faculty member in the Physics Department at the University of Arizona.
now an Excellence Chair at Laboratoire d'Astrophysique de Marseilles.
(CCAPP Fellow), now a faculty member in Physics at the University of Athens.
(CCAPP Fellow), now working in the data science industry in the Bay Area.
(Hubble Fellow), now a faculty member in Physics at University College London.
(CCAPP Fellow), now a faculty member at Shanghai Jiao Tong University (SJTU).
