Alessandro gained a First Degree cum laude in Mechanical Engineering in 2003 from the “University of Ancona” in Italy, after which he worked for two years at Lucci Collettori Spa (Ancona, Italy) where he supervised the design and production of commutators for electric motors. In 2006 he worked for 6 months at Seagate Technology Inc. and he then began a PhD at Imperial College London in the Thermo-Fluids Division focussing on aerodynamic study of single and twin-entry mixed flow turbines under unsteady conditions. As a part of his research, he also studied heat transfer effects occurring in turbochargers.

After completing his PhD in 2010, Alessandro worked as Research Associate at Imperial College London. He acted as research co-investigator in projects looking at engine downsizing, waste heat recovery, and mild-hybridization of powertrain technology in passenger vehicles as well as in optimization and design of novel turbine concepts. He collaborates extensively with world leading OEMs in powertrain R&D (Jaguar and Land Rover, Lotus, Ford, CAT, MHI, Honda, ABB, etc.).

In 2013, he joined Nanyang Technological University as an Assistant Professor. His responsibilities include teaching undergraduate courses, run lab-tutorial, supervising PhD students and FYPs. Alessandro’s research activity in NTU encompasses several aspects related to propulsion, energy efficiency and thermal energy recovery and management. Examples of his current research include the study of waste heat recovery such as ThermoElectric Generators design and analysis, Organic Rankine Cycles optimization, Turbocharging and Thermal Energy Storage; Alessandro is also championing the effort on Cold Energy Recovery and Cold Economy in Singapore.

Besides his academic activity Alessandro has also worked for three years (2010-2013) as engineering consultant under ICON (Imperial College CONsultant). In 2012, he founded a UK-based engineering consultancy company (RhodoConsultants, ) offering design, test and advice on energy efficiency, turbomachinery and waste heat recovery systems. Alessandro also acts as reviewer for several engineering journals (ASME, SAE, IMechE, Elsevier), collaborates as freelancer with the automotive magazine Torque (published in Singapore).
