As of April 2017, I have left academia for industry!

As a theoretical astrophysicist, I worked as a Research Assistant Professor at Stony Brook University's Department of Physics and Astronomy.

My research focuses on the origins, growth and dynamics of (big) black holes.

One of the great discoveries of the last 20 years is that all or most massive galaxies in our cosmic neighborhood appear to each have a "supermassive" black hole in their centers, with masses millions and even billions of times that of the Sun. Our own Milky Way has a black hole weighing in at 4 million solar masses. Somewhat preposterously, supermassive black holes can power some of the brightest phenomena in the Universe. When they get a nice meal of rich gas, they light up the gas, outshining their own galaxies by as much as a thousandfold.

I work on:
binaries and mergers of supermassive black holes (what happens when galaxies each with a supermassive black hole collide and merge),
the cosmic origins and evolution of supermassive black holes (how these monsters formed in the first place),
and the theory of gas accreting onto black holes and other compact objects (how they light up the gas they consume, and what we can learn from this).
