Tito R. Vargas
Assistant Professor
Tito Raúl Vargas Hernández graduated in Telecommunications Engineering from Universidad Santo Tomás (USTA), Bucaramanga, Colombia, in 2003. He received the M.Sc. in Telematics Engineering in 2007 and the PhD in Telecommunications in 2023 from the Universitat Politècnica de València (UPV). He worked with the COMM group at iTEAM from 2005 to 2010 and has been a lecturer and researcher at USTA since 2010. In 2022 he joined iTEAM as a research engineer and later worked there as a postdoctoral researcher. He is now an Assistant Professor (Profesor Ayudante Doctor) in the Department of Communications (DCOM) at UPV and a member of iTEAM. His research covers multimedia distribution over IP/optical networks, energy-efficient Ethernet, QoS in high-speed networks and the Internet of Things.
