I am a professor in the Physics and Astronomy Department at Northwestern University, working mainly at the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA). Since 2013 I have served as Lead Editor for The Astrophysical Journal Letters, one of the AAS Journals.
Research in my group spans a wide range of topics in theoretical astrophysics, including exoplanets and planet formation; the dynamics of dense stellar systems (globular clusters, galactic nuclei, and young star clusters); hydrodynamic stellar interactions such as stellar collisions and mergers, binary coalescence, common-envelope evolution, and tidal disruptions; and relativistic astrophysics, including neutron stars and black holes, gravitational waves, and radio pulsars. Recent work has focused on the formation of gravitational-wave sources and massive black holes through stellar-dynamical processes, using supercomputer simulations and artificial-intelligence methods.
