I am currently a Research Associate with the Faculty of Engineering at the University of Bristol, working on the RERUM project (FP7/2007-2013 grant no 609094) on the design and implementation of a security framework for the IoT, driven by the requirements of Smart City applications. I am also affiliated with the ForToo project, an ISEC 2010 action grant on the development of advanced forensic tools against Internet abuse, with focus on forensic analysis of android devices and wireless sensors.

Previously, I was with Computer Science at Loughborough University, working as a full-time research associate. My work there focused on Wireless Sensor Networks and the Internet of Things. LU own about 500 devices from Sensinode (USB NanoRouters (N601) and NanoSensors (N740)). They are equipped with the CC2430 System-on-a-Chip (SoC). In addition to research activities, I was developing software for those devices using the Contiki Embedded OS.

I am an active member of the contiki developers team, maintaining a bunch of hardware ports. One is for the TI CC2538 SoC Development Kit (SmartRF 06 Evaluation Boards with CC2538 EMs). More info on this Contiki platform here. Another port is for the somewhat older Texas Instruments CC2530DK (SmartRF 05 EBs with cc2530 EMs and cc2531 USB Dongles). Lastly, there is a port for the Sensinode devices discussed above. For more information on the CC2530DK and Sensinode ports, have a look at their page on the Contiki wiki. Some further info can be found in this entry in my blog. Last but not least, I've contributed Contiki's support for 6LoWPAN multicast. More information here.

From 1999 until early 2009, I was a member of the Computer and Communication Systems Laboratory (Department of Informatics - Athens University of Economics and Business).

While there, I conducted research is in the field of Computer Networks and Distributed Systems. More specifically, I focused on Distributed Service Management, Network Management, Wireless and Mobile Networks, Network Security. The result of my collaboration with the CCSLAB was my participation in multiple R&D projects financed by the greek government, the EU as well as private companies. Lastly, I served as the laboratory's administrator for the same period, performing maintenance of user workstations (both windows and Linux based) as well as the laboratory's web and mail server (Linux).

In the past I have worked for the Omiros College (now called "Aegean College"), a Greek higher educational institution offering University of Huddersfield undergraduate degrees in Athens as well as Edexcel International HND qualifications. I served as "Pathway Leader" for the "BSc (Hons) in Multimedia" program. Furthermore, I was supervisor for final year projects of the "BSc (Hons) Multimedia Computing" program.

Between 2002 and 2008, I provided supervision support for more than ten undergraduate and postgraduate theses on topics related to computer networking. I also assisted with the teaching of undergraduate as well as postgraduate modules in the Department of Informatics of the Athens University of Economics and Business.

Over the past years I have developed a variety of IT skills. I have extended knowledge of IP networks and related protocols and services. I am a good C/C++ code writer. I have good knowledge of object oriented design techniques. I am very comfortable with the Linux operating system.

I speak excellent English and Spanish. I also speak some French.
