ECS Academic Integrity Officer<br>Admissions Tutor for Electronic Engineering<br>A-level Teachers Workshop Leader<br>SEMS Group Webmaster<br>Associate Editor of IET Circuits, Devices and Systems

Alex Weddell is a Lecturer in the Smart Electronic Materials and Systems Research Group, in the School of Electronics and Computer Science at the University of Southampton, UK. The school is the best in the UK for the quality and volume of research in Electrical and Electronic Engineering (REF 2014). He is also a core member of the ARM-ECS Research Centre and a member of the management group for the Centre for IoT and Pervasive Systems. He acts as Associate Editor for the IET Circuits, Devices & Systems journal.

His main research interests are in wireless sensing, energy harvesting systems, and intelligent sensing for monitoring the health of machines. He is most interested in research that's aimed at solving real problems, and demonstrated using physical prototypes. He is currently supervising (or co-supervising) around seven PhD students.

Alex leads two second-year modules on Advanced Electronic Systems and Computer Engineering, and teaches a third-year undergraduate module on Computer Networks. He supervises many practical third-year individual projects, fourth-year industrial Group Design projects, and MSc summer projects.

He was awarded the MEng Electronic Engineering (first-class honours) at the University of Southampton in 2005, followed by a PhD, thesis entitled "A comprehensive scheme for reconfigurable energy-aware wireless sensor nodes", in 2010. He contributed to the Data Information Fusion Defence Technology Centre (DIF DTC) 'Adaptive Energy-Aware Sensor Networks' project and worked under the EPSRC platform grant 'New Directions for Intelligent Sensors'. He has experience with a range of energy harvesting devices and has developed a platform which supports a mix of energy sources to power an energy-aware wireless sensor node. He worked on the 'Next Generation Energy-Harvesting Electronics: Holistic Approach' project, looking at energy device modelling and system-level design approaches.before being appointed as a Lecturer in February 2013.

He is currently a co-investigator on an EU Clean Sky 2 project "Intelligent Integrated Bearing System", developing self-powered smart bearings for jet engines. He is also a co-investigator on the EU Horizon 2020 project "EnABLES: European Infrastructure Powering the Internet of Things" and the EPSRC Platform project "Wearable and Autonomous Computing for Future Smart Cities".

Alex is also passionate about outreach. He runs electronics activities for the annual Electronics & Computer Science Taster Course, and leads an annual A-level Teachers Workshop and other teachers' CPD activities aiming to get hands-on electronics into the classroom. He contributed to development of Southampton's A-level Physics: Music Mixer and A-level Computing: Logic & Arithmetic kits.
