Professor Jeff Kettle

Professor of Electronic Engineering (Electronic & Nanoscale Engineering)

Biography

I’ve been based in the James Watt School of Engineering since 2020. I studied at Cardiff and Swansea Universities, where I worked on III-V LEDs, and then worked in a variety of industrial and academic settings, before being made a lecturer at Bangor University in 2012. During my time as a lecturer, I acquired grant funding from the EPSRC, Royal Society, Royal Academy of Engineering, Interreg, Welsh Government, InnovateUK and European Commission, worth around £3m. I also have experience undertaking commercial work with a range of semiconductor, electronic and engineering companies, particular in areas related to failure analysis and sustainability and reliability improvement. I have acted as an external consultant and on the Advisory board for a number of start-ups and established companies.

Research interests

Currently, our research groups focuses on improving the sustainability of Electronics and ICT equipment and the development of its Circular Economy. We undertake detailed Life Cycle Assessment (LCA) of electronic and photonic systems. We reduce the environmental impact of microelectronic and optoelectronic devices and systems through improving the design; Design for Reliability, Design for Recyclability, or through the development of biodegradable or reusable electronic substrates, conductors and ICs. We also work on new and greener methods to recover Critical Rare Metals (CRMs) from electronics.

We also develop sensors and wireless sensors systems that enhance sustainability; for example, agri-tech sensors, monitoring of building usage, wearable sensors, and sensors that optimise manufacturing process performance. I am also keen to work in an interdisciplinary fashion and have experience working with environmental scientists, biologists, medical professionals as well as organic and inorganic chemists to produce functional devices with new materials.

In addition, my group actively works in solar energy and energy harvesting, especially with organic and perovskite solar cells.

I run the ENE groups semiconductor packaging laboratory, which includes wire bonders, die bonder and sintering systems
