Prof. Roberto Sabadini is Full Professor of Solid Earth Geophysics at the Department of Earth Sciences, University of Milano, Italy. His focus is on the role of Earth's viscoelasticity, particularly within the frame of an analytical approach, applied to a variety of geophysical phenomena, from postglacial rebound to those related to mantle density anomalies, from secular polar motion to post-seismic deformation. This modelling looks at the Earth in an integrated fashion and links the physics of its interior with the newly acquired gravity and deformation data from space geodesy.Prof. Dr. Bert Vermeersen is Full Professor of Planetary Exploration at the Faculty of Aerospace Engineering and at the Faculty of Civil Engineering and Geosciences of Delft University of Technology in The Netherlands. He is also a Senior Researcher on sea level change at the Royal Netherlands Institute for Sea Research NIOZ in The Netherlands. Prof. Vermeersen's focus of his planetary exploration research is on the moons of Jupiter and Saturn. At NIOZ his research concentrates on sea level change for both the present day and for geological periods.Dr. Gabriele Cambiotti is Researcher at the Department of Earth Sciences at the University of Milano, Italy, where he teaches the courses of Seismology and Mathematical Methods for Geophysics. His research focuses on viscoelastodynamics and the modeling of glacial isostatic adjustment, mantle convection and seismic cycle. He studies basic physical and mathematical issues related to viscoelastic deformation. Long term Earth's rotation and gravitational seismology are also keys in his research.
