Since 2014, I am Research Associate at the University of Luxembourg (SnT) and an active member of the VehicularLab team (Security and Networking Research Group). My research interests focus on sensor networks and can be decomposed into three complementary topics: intelligent transportation, sensing and distributed systems

Short bio. I became interested in telecommunication networks as a graduate student at the University of Picardie Jules Verne, Amiens, France. I attended a research-oriented program during which I started working in the field of wireless sensor networks (WSNs). Despite their energy and resource limitations these networks have unrivalled flexibility, which makes them ideal for deployment in a wide variety of environments. Specifically, during my MS thesis, I carried out a number of studies on WSNs and the security mechanisms they offer. Then, as a PhD candidate at Telecom ParisTech, Paris, France, I focused on WSNs applied to intelligent transportation systems (ITS). Specifically, I studied how sensors equipped with magnetometers and short-range wireless radio interfaces can be deployed along the road network so as to detect the passage of vehicles and exchange traffic count information. By means of in-network processing of such data, a WSN can manage traffic flows in a distributed way and without need for a central control point as it happens today – which implies lower latencies as well as more capillary, reactive and fault-resistant management of road traffic. I studied the topological features of WSN architectures for traffic management in large-scale urban areas, and developed distributed algorithms that run on the WSN and ease traffic congestion by means of adaptive traffic light control. Since then, I have been working on other aspects related to sensor networks, including activity detection, mobile and wearable computing.
