About me

Ph.D. Alessandro (aka Alex) Carrega is a Software and Network Engineer. He is currently a Senior Researcher at the National Inter-University Consortium for Telecommunications (CNIT) located in the Genoa (Italy) research unit.

He took part in the activities of many national and European projects (e.g. H2020 ASTRID, GUARD, ARCADIA and INPUT, FP7 IP ECONET, PRIN EFFICIENT, FIRB GreenNet, and FIWARE) and he is an active reviewer for many different international journals and conferences (IEEE and ACM).

He has co-authored several papers in international conference proceedings. In 2010, he won the best paper award at the 3rd Int. Workshop on Green Communications (GreenCom 2010) co-located with the IEEE GLOBECOM Conference. In 2011 he was a Visiting Ph.D. Scholar at Portland State University (PSU), Portland, OR, USA under the supervisor of Prof. Suresh Singh as an active member of the FINE2 Italia – USA collaboration project.

He received the B.S. and M.S. degrees in Computer Engineering and the Ph.D. degree in Green Networking from the University of Genoa in 2005, 2007 and 2013, respectively. Alex Carrega’s research is on networking (energy-aware, performance optimization, and virtualization), software routers, NFV and SDN (OpenFlow), container-orchestration system for automating computer application deployment, scaling, and management (Kubernetes) and cloud computing platforms (Openstack).

Finally, he is involved in collaboration with many industries, such as Telecom Italia, Broadcom, Nokia, Ericsson, Huawei, etc., and industrial fora, like GeSI.
