Biography

I am a PhD student/research assistant at the Institute of Computer and Network Engineering at the Technische Universität Braunschweig, Germany. I received my Master's degree in Computer Science (2018) from the Institute of Informatics of the Federal University of Rio Grande do Sul (UFRGS), Brazil. In addition, I hold a Bachelor's degree in Information Systems (2016) from the Federal Univesity of Santa Maria (UFSM), Brazil. My current research interests include Software Defined Networks, Wireless ad-hoc Networks, Flying ad-hoc Networks, Next Generation Networks, Future Internet, Internet of Things and Software Defined Radio.
