Curriculum Vitae:

Anezina Solomonidou

Anezina Solomonidou is a Planetary Geologist. She specializes in the study of the general geology and more specifically in volcanology and spectroscopy of the icy moons of the outer solar system. She studies the nature of the surface and the intecorrelation between the surface, the atmosphere and the interior of planetary bodies. Since 2014, she is a Postdoctoral Fellow at the Jet Propulsion Laboratory (JPL) working with Dr. Rosaly Lopes. She holds collaborations with various scientists and institutions from all over the world such as the Observatory of Paris, the German Aerospace Center (DLR), the Lunar and Planetary Laboratory (LPL) etc.

  • PhD in Astronomy and Astrophysic, Observatoire de Paris – LESIA, Paris, France (co-tutelle) (2013)
  • MSC in Geosciences - Planetary Geology, University College London (2008)
  • BS in Geology, University of Patras (2007)

Research Interests
  • Geology of icy moons
  • Spectroscopy and Radiative transfer analysis
  • Cryovolcanism and Tectonic deformation of icy satellites
  • Surface evolution
  • Interior dynamics

My research work is focused on the study of the surface of Titan and other satellites of Saturn, such as Enceladus. A central point of my research is to inter-compare these planetary bodies and also search for analogues with the Earth, a perspective that combines both my geological and planetological background. My main interest is the interpretation of the geological features of Titan in addition to the correlation with the terrestrial geological terrain in order to have a ‘view’ of the past history and/or the future evolution of their geology. During my postdoctoral thesis I try to answer some of the current fundamental questions - arising from the Cassini-Huygens and ground-based observations. I study more specifically the active zones i.e. regions that are subject to change over time, with a view to the finding out whether cryovolcanoes exist on Titan. This, will hopefully provide us with insights on the unknown aspects of Titan, i.e. whether the body was or is still active, whether there is connection and interaction between the interior, the surface and the atmosphere (methane reservoir), as well as, what is the evolution of this body based on geological evidence. Moreover, from an astrobiological point of view, is the important issue of finding places like Earth that could support the existence of life. Evidence of cryovolcanic processes on Titan would mean that liquids and heat are present and could form the habitat for life.
