Personal homepage

Dr Geoff Merrett is an Associate Professor in the School of Electronics and Computer Science, based in the Electronic and Software Systems Group. He was awarded a first class honours degree in Electronic Engineering from the University of Southampton in 2004, where he subsequently studied for a PhD. He was awarded his PhD in March 2009 for his thesis on "Energy- and Information-Managed Wireless Sensor Networks: Modelling and Simulation." His research interests are in energy-aware wireless sensing and sensor networks, energy harvesting, modelling and simulation, pervasive healthcare and wearable devices. Dr Merrett is a Co-Investigator on the EPSRC-funded £5.6M PRiME Programme Grant (where he leads the applications and cross-layer interaction theme), the £11.6M SPHERE IRC, and "Continuous on-line adaptation in many-core systems: From graceful degradation to graceful amelioration". He has previously been a Co-Investigator on "Next Generation Energy-Harvesting Electronics - A Holistic Approach" (where he is also led the demonstrators theme) and the "Energy Harvesting Network" (which he continues to co-manage), and was a named-researcher on the project "Platform: New Directions for Intelligent Sensors". He was also the recipient of a competitive 'Adventures in Research Grant' from the University of Southampton on "Design and Human Evaluation of Haptic Devices for Hand Rehabilitation from Sensory Deficits due to Neurological Impairment (Principal Investigator), an interdisciplinary project with researchers from the Faculty of Health Sciences, which subsequently led to being awarded further funding in this area by the NHS/TSB. His research team currently consists of 3 members of research staff, 13 PhD students, 3 visitors, and a number of project students, and he has previously supervised 10 research students through to completion and managed 25 members of research staff and interns. 

Dr Merrett is actively involved in the School's Pervasive Systems Centre (PSC), and founded and chairs an interest group on wireless sensing (WiSE) as part of the "sensor networks" research theme. He has authored a number of journal and conference publications in the area of wireless sensor networks, co-edited a book on "Wireless Sensor Networks: Application-Centric Design", and contributed a chapter on "Wireless Devices and Sensor Networks" in the book "Energy Harvesting for Autonomous Systems." He is a member of the IET and IEEE, and Branch Councillor for the University's highly successful IEEE Student Branch. He is an active reviewer for a number of prestigious international journals, has served on a number of technical programme committees for conferences, and has co-organised the UK's leading Energy Harvesting conference for the past two years. He is giving the keynote talk at EnHaNSS 2012, was awarded a best paper award for his research into the DejaView system (a wearable system incorporating low-power wireless devices), and nominated for a best paper award at DATE 2011 for research into modelling and simulating energy harvesting sensor nodes.

He lectures on digital circuits and microprocessors, coordinates the first year electronic and electrical lab programme, co-organises the Electronic Engineering programme's flagship second year design exercise, supervises a number of undergraduate and MSc projects, and is Senior Admissions Tutor for the undergraduate Electrical and Electronic Engineering (EEE) degree programme. He is also the University's representitive on the UK Electronics Skills Foundation, a collaboration between industry and universities which, alongside promoting a career in electronics, provides scholarships, summer employment and industrial mentoring to many of our undergraduates. Further information about Dr Merrett can be found on his University webpage and academic profile.
