Bachelor of Science Degree in Telecommunication Engineering by the University of Vigo, Spain (2007) in the speciality of Communications, he has developed  his professional career in the field of voice and data networks, taking part in many projects for Tele2, Vodafone and R Cable ISPs. At the same time he kept linked to his branch of academic knowledge, receiving the Master of Science Degree in Radiocommunication and Electromagnetic Engineering from the University of Vigo in 2010. At present he is working with the Photonics group in the University of Vigo researching on photonic crystals aiming to get his Ph.D. degree.
