Curriculum Vitae
In 2004 she graduated in Mechanical Engineering at the University of Genoa receiving the official mention as “archival publishing level”. In the same year she joined the Internal Combustion Engines Group (ICEG) of the University of Genoa.

In 2005 she achieved the Doctorate degree in Fluid Machines Engineering at the same University, discussing a final thesis entitled “Experimental study on turbocharging systems for automotive engines” in 2008.

From 2005 to 2011 she was Research Assistant at DIMSET.

Since 2011 she is in the permanent staff of University of Genoa as Assistant Professor at the Department of Mechanical, Energetics, Management, Transportation and Mathematical Models Engineering (DIME).

She is the chief of the research activities developed at the Intake and Exhaust Components Test Facility.

She is the author of more than 30 papers presented at conferences or published in international journals.


  • Since 2004 she was involved in teaching and laboratory activities, participating to the board examiners in different Second Level Degree Courses at University of Genoa: Internal Combustion Engines (Second Level Degree in Mechanical Engineering), Internal Combustion Engine 1 (Second Level Degree in Mechanical Engineering), Automotive Engine 1 (Second Level Degree in Mechanical Engineering),  Energy Systems for Transportation and Environmental Impact 1 (Second Level Degree in Transports and Logistics)
  • Supervisor and co-supervisor of about 35 degree thesis
  • Tutor of two PhD students
  • Lecturer in Sistemi Propulsivi a Ridotto Impatto Ambientale offered to Mechanical Engineering at University of Genoa (A.A. 2011/2012, 2012/2013, 2013/2014, 2014/2015).
  • Lecturer in Macchine e Sistemi Propulsivi offered to Safety and Security Engineering: Transportation and Territorial Systems at University of Genoa (A.A. 2013/2014, 2014/2015).
