Gediminas Juzeliūnas is a principal researcher and a deputy director at the Institute of Theoretical Physics and Astronomy of Vilnius University, Lithuania. He is also professor of physics at Lithuanian University of Educational Sciences in Vilnius. Dr. Juzeliūnas completed his Ph.D. in 1986 in theoretical condensed matter physics at Vilnius University, studying optical properties of excitons in confined geometries. Subsequently he held a two-year postdoctoral appointment at the University of East Anglia, England, shifting his research area towards quantum optics. Dr. Juzeliūnas was a Humboldt Research Fellow at the University of Ulm, Germany (1997–1998), and a Fulbright Scholar at the University of Oregon in the US (2000–2001). Dr. Juzeliūnas received a National State Prize for Science of Lithuania in 2008 and a Vilnius University Rector’s award in 2010. His current research focuses on ultracold atomic gases, slow light, metamaterials, and graphene. This includes a pioneering theoretical work on light-induced gauge potential for ultracold atoms.
