Astrophysics Research

jay I am a professor in the Department of Physics and Astronomy at Michigan State, where I am the graduate director for our astronomy PhD program and associate chair for astronomy.

Recently my work has focused on studying compact objects, especially on searches for black holes and neutron stars in globular clusters, neutron star binaries among Fermi gamma-ray sources, and intermediate-mass black holes. This work is supported by a Packard Fellowship and grants from NSF and NASA.

My research group at MSU includes postdoc Ryan Urquhart, graduate students Rebecca Kyer and Thomas Do, and several undergraduates. Some students are co-advised with Laura Chomiuk.

I've been a member of Stars, Milky Way, and Local Volume science collaboration for the Rubin Observatory since 2008, and now sit on the Rubin Survey Cadence Optimization Committee.

Previously, I was a core member of the SAGES group, which studies extragalactic globular cluster systems as a means to understand galaxy formation. I got my PhD in astronomy at UC-Santa Cruz/Lick Observatory. From 2007-2012 I was a Hubble Fellow and Menzel Fellow at the Harvard-Smithsonian Center for Astrophysics.

You can find the catalog of M31 globular cluster velocity dispersions, masses, mass-to-light ratios, and radii here. See Strader et al. (2011, AJ, 142, 8) or send me an email if you have questions.
