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 60 publications in refereed journals (out of which 9 letters) and more than 40 contributions to conference proceedings. His research topics include: 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 more than 2700 citations (excluding self-citations) with an h-index of 34 (NASA-ADS data).

He is the author of a highly-cited review article in Living Reviews in Relativity and co-author of a new book, entitled “Rotating Relativistic Stars”, in the highly-acclaimed series Cambridge Monographs on Mathematical Physics. He has presented more than 20 invited talks at international conferences and he gave a series of invited lectures at 4 international summer or winter schools for advanced graduate students and post-docs on relativistic astrophysics and numerical relativity. He was P.I. in 7 international or bilateral research grants (including two Marie-Curie post-doctoral fellowships) and participated in more than 10 other research grants. He is representative of Greece in the management committee of the ESF COST project "Exploring Fundamental Physics with Compact Stars" and is participating in the CTA Consortium and in the LOFT proposal for a new ESA X-ray mission.

He has 15 years of experience in supervising and training young researchers, including several international post-doctoral researchers, several Ph.D. students, and a large number of M.Sc. and B.Sc. students. At the Aristotle University of Thessaloniki, Nick Stergioulas is currently teaching "Astronomy and Astrophysics", "General Relativity", "Numerical Analysis", "Astrophysics", "Programming Tools" and "Calculus I". He is the author of the public domain code "RNS" for constructing equilibrium models of rotating relativistic stars, which has been used extensively by the community in the last 15 years.

Nick Stergioulas has served as the Secretary of the
Hellenic Society for Relativity, Gravitation and Cosmology (2014-2016), while he also served as an elected member of the governing councils of the Hellenic Astronomical Society (2008-2010) and the Hellenic Society for Relativity, Gravitation and Cosmology (2012-2014). Recently, he was elected to a second term on the governing council of the Virgo-Ego Scientific Forum (VESF), which supports the VIRGO gravitational-wave detector.

He is currently an associate editor for the journal
"General Relativity and Gravitation" (Springer).
