I am currently working on finishing my Ph.D. here at Minnesota under the supervision of Prof. Kapusta in the Nuclear Theory group.
In a previous research project, I investigated the formation of small black holes in the early universe, a few microseconds after the Big Bang.
My current line of research involves attempting to describe collective properties of the 'quark-gluon plasma', a state of matter created in the Relativistic Heave Ion Collider (RHIC) at Brookhaven National Labs. I use gauge/gravity duality techniques to perform these calculations; these are based on the conjecture that a strongly interacting field theory may be described by a 'dual' gravity theory in one extra space-time dimension.
