Nick Stergioulas is known for his contributions to the study of the equilibrium and stability of rotating relativistic stars, of relativistic accretion disks and of strongly-magnetized neutron stars (magnetars). He received his Ph.D. from the University of Wisconsin-Milwaukee, under the supervision of John L. Friedman, in 1996. He was a post-doctoral researcher at the Albert-Einstein-Institute, Potsdam (MPA for Gravitational Physics, 1998-1999) before joining the Department of Physics at the Aristotle University of Thessaloniki as a faculty member. He has more than 210 publications, out of which more than 120 refereed publications. His research topics include: Gravitational-wave astronomy; Compact stars as sources of gravitational waves; Equilibrium and instabilities of rotating relativistic stars; Nonlinear oscillations of relativistic stars; MHD oscillations in relativistic models of magnetized neutron stars; Numerical relativity; Interaction of gravitational waves with plasma; and Relativistic accretion disks. His publications have received a total of more than 10,100 citations with an h-index of 52.
