Andrés Ferragut

Andrés FerragutAndrés Ferragut obtained his Ph.D. in Electrical Engineering from Universidad de la República, Uruguay (2011). He obtained his BS degree in Telecommunications from the same institution (2004). He also studied mathematics. From 2000 to 2010 he was a research and teaching assistant in the Mathematics and Electrical Engineering departments.

From 2004 to 2006 he was also a research student at the École Nationale Supérieure des Télécommunications, Paris, France. He also worked in consulting for national and international institutions in the analysis and design of telecommunication networks.

He joined the MATE Research Group in February 2007, and he currently is Assistant Professor on Telecommunication Networks at the School of Engineering of Universidad ORT Uruguay and Level I Researcher in the National Research System.

He specializes in communication networks modelling, particularly by using probability theory, stochastic processes, queueing theory and control theory.
