I am an Assistant Professor of Physics and Astronomy at Northwestern. My interests include high-energy astrophysics processes powered by compact objects, black holes and neutron stars.   I use a variety of tools -- ranging from pencil and paper calculations to large-scale computer simulations -- to construct quantitative models of physical processes occurring near these objects and then use these models to improve our understanding of these enigmatic systems, e.g., measuring black hole masses, spins, and the strengths of magnetic fluxes threading their event horizons.
 

My simulation image makes it to a book cover:


Disk-jet accretion system in a 3D general relativistic magnetohydrodynamic simulation
Ordered, dynamically-important magnetic fields launch a pair of relativistic jets and remove the angular momentum from the accreting gas even as they obstruct its infall into the black hole in a 3D general relativistic magnetized fluid dynamics simulation
