Leonardo Goratti received his PhD degree in Wireless Communications in 2011 from the University of Oulu-Finland and his M.Sc. in Telecommunications engineering in 2002 from the University of Firenze-Italy. From 2003 until 2010, he worked at the Centre for Wireless Communications (CWC) Oulu-Finland first as a researcher and then as a PhD student. His research interests cover Medium Access Control (MAC) protocols for wireless personal/body area networks and wireless sensor networks, as well as routing protocols for sensor networks. His research interests cover also UWB transmission technology and 60 GHz communications. From 2010 until early 2013 he worked on MAC protocols for cognitive radios and spectrum sharing techniques at the European funded Joint Research Centre (JRC) of Ispra, Italy. Recently he joined the Research Centre CREATE-NET Trento-Italy where he is currently working in the European project ABSOLUTE on LTE-based device-to-device communications in the context of public safety scenarios.
