Brief biography:


Alvaro Barradas received the four-year first degree in computer science and the Ph.D degree in electronics engineering and computing from the University of Algarve, Faro, Portugal, in 1995 and 2009 respectively. His major field of study has been on load balancing for optical networks.
Currently he is an Auxiliary Professor at the Faculty of Science and Technology from the University of Algarve. His previous professional experience includes two years working on system test for computer science and telecommunications consulting companies in Lisbon and Dusseldorf. His current research interest includes the study and simulation of hybrid networks where QoS provisioning is challenging.
He is a member of the Center of Electronics Optoelectronics and Telecommunications (CEOT) at the University of Algarve, a research center supported by the Portuguese Foundation for Science and Technology.
