Home page of Roman Geiko

I am a PostDoc at the Physics & Astronomy department at UCLA supervised by Ryan Thorngren. Before that, I was a graduate student at Rutgers advised by Greg Moore. I am a mathematical physicist interested in topological condensed matter physics, quantum information, and high-energy theory.

Here is my CV and Google Scholar
