I am Tomoki Ozawa, a senior research scientist at iTHEMS. I am originally from Japan. I finished my PhD in the University of Illinois at Urbana-Champaign in the US, and then spent five years as a postdoc at the BEC Center (Bose-Einstein Condensation Center) at the University of Trento in Italy. Then, after spending three months in Brussels, Belgium, I came back to Japan and joined RIKEN iTHEMS this April. My main research interest is in the intersection between condensed matter theory and AMO (Atomic, Molecuar and Optics) theory. In particular, I have been working on many-body and topological physics of ultracold atomic gases and photonics. My style of research is to try to understand target systems in as simple way as possible; this sounds rather trivial, but it often leads to something unexpected in the end. In iTHEMS, I hope to collaborate with people from various backgrounds and start something exciting together.
