Costanza graduated in Physics from the University of Genoa in 2003. She did her diploma thesis work at the Astronomy and Space Physics department of Uppsala University under the supervision of Prof. Vladimir Pavlenko, focusing on the reduction of transport flows in magnetized plasmas
. She obtained her PhD degree
in Plasma Physics at the Plasma Physics Research Center at the Swiss Federal Institute of Technology, Lausanne (EPFL) in 2009, under the supervision of Dr Olivier Sauter, where her work on Thermonuclear Fusion research included, among other areas, the design of operational scenarios with high-output power
for the first prototype of a thermonuclear fusion reactor, the ITER tokamak
. During this time, she has also been assistant lecturer in General Physics and authored some 20+ peer-reviewed publications. After (too short...) a sabbatical in South America, Costanza joined Frontiers at the end of 2009 as the main coordinator of the Marketing and Communication office. In 2010, she took over leadership of the editorial office at Frontiers, which grew under her watch from 10 to over 40 "Frontiers in"
titles. In 2014, Costanza joined the Boston Consulting Group.
