Sergis Nick

Dr. Nick Sergis was born in Athens on July 1973. He received his PhD in Astrophysics and Space Physics from the University of Athens in 2006. Since April 2006 he works as a Researcher at the Office of Space Research and Technology of the Academy of Athens and since February 2017 he is also an Adjunct Researcher at the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens (NOA). Dr. Sergis is a member of the Cassini/MIMI Scientific Team, the IAASARS Space Research and Technology Group and the Uranus Pathfinder Consortium. He has published 56 papers, 3 as invited book chapters and 53 in peer-reviewed scientific journals (Nature, Nature Physics, GRL, JGR, ApJL, Solar Physics etc.) with over 900 citations (h-index of 18). He has also chaired several conference sessions, presented more than 70 papers in international conferences and given over 20 invited talks and seminars. Dr. Sergis has been continuously serving as a reviewer for most scientific journals of his field (JGR, GRL, Space Science Reviews, Annales Geophysicae, etc.) and for proposals submitted for funding to NASA (NSPIRES system). In 2008, he was elected “best reviewer in the field” by the editorial board of Annales Geophysicae and in 2009 he received the “NASA Group Achievement Award” as a member of the Cassini/MIMI Team. Dr. Sergis is a co-leader of the Plasma Radial Transport Team, selected for funding by the International Space Science Institute (ISSI) in 2014. His research interests include Space and Planetary Physics, Magnetospheric Data Analysis with emphasis on the Outer Planets and their moons, Magnetosphere-Ionosphere Coupling, and Solar Wind Dynamics. He participates in a number of ongoing scientific collaborations with institutes from the USA, the UK, Germany and Argentina. Dr. Sergis has supervised or co-supervised one post graduate and over 15 undergraduate students. He is a member of the American Geophysical Union (AGU), the European Geosciences Union (EGU) and the International Astronomical Union (IAU).
