Susanna Zerbini

Susanna Zerbini (born 1948) is an Italian geophysicist, geodesist, and geodynamicist. She is known as a pioneer in developing and applying satellite geodesy for research in geodynamics and Earth system sciences.

Education and career Zerbini completed classical secondary school education (including Latin and Greek) and then decided to become a scientist. In 1972 she graduated from the University of Bologna with a Ph.D. (Laurea) in physics. From 1973 to 1981 she was supported by fellowships from the Consiglio Nazionale delle Ricerche (Italian National Council of Research) and Zonta International. From 1975 to 1976 and again from 1978 to 1979 she held appointments as a visiting scientist in geoastronomy at the Harvard-Smithsonian Center for Astrophysics. At the University of Bologna, she was from 1981 to 1987 a research associate, from 1987 to 2011 an associate professor of geodesy, and from 2011 to 2018 a full professor in the department of physics. In 2018 she retired as professor emerita.

Zerbini played a key role in explaining anomalous orbital effects for PAGEOS (PAssive Geodetic Earth Orbiting Satellite) — a balloon satellite was launched by NASA in June 1966. PAGEOS was important in research on direct solar radiation and terrestrial albedo radiation. She identified the flux of micrometeoroids in the near-Earth environment as the cause of unexpected oblateness and precession of PAGEOS. She developed models for precise computations of the orbits of LAGEOS-1 and LAGEOS-2. Her research was important for using the LAGEOS data for precisely determining Earth's crustal motion, especially for the Mediterranean region and the San Andreas Fault. She was the leader for Italy's science participation in the LAGEOS-2 mission jointly sponsored by the USA (via NASA) and by Italy. In the first decade of the 21st century, she and her colleagues used GPS and large, coordinated ensembles of superconducting gravimeters to study changes in Earth's mascons for the purpose of better understanding of tectonic movements.

Zerbini has served on numerous scientific committees, panels, and advisory boards. She was from 2007 to 2008 a member of the Board of Administrators of the Italian Space Agency (ASI), from 2008 to 2010 a member of the Waldo E. Smith Medal Committee of the American Geophysical Union (AGU), and from 2009 to 2011 the chair of the Vening Meinesz Medal Committee of the European Geosciences Union (EGU). She was from 1992 to 1996 an associated editor for geodesy in the AGU's Journal of Geophysical Research-Solid Earth. For Elsevier's Journal of Geodynamics, she was from 1996 to 2002 an associate editor and is since 2002 a member of the journal's editorial board.

Zerbini was elected in 1999 a Fellow of the International Association of Geodesy (IAG). In 2001 she was awarded the "Gold Badge" of the European Geophysical Society (EGS), which was merged in 2002 into the European Geosciences Union (EGU). In 2009 she was awarded the EGU's Vening Meinesz Medal.
