'Improving the sustainability of electronic materials'
I joined the University of Glasgow in 2020 and my new role is as a senior lecturer in ‘sustainable electronics.’ In this role, I will develop methods to reduce the environmental impact of electronic, optoelectronic and photovoltaic devices. This involves improving the long-term reliability of devices and their ability to operate in harsher environments, as well using materials that are less toxic. I also develop sensors systems that enhance sustainability; for example, agri-tech sensors, wearable sensors, and sensors that optimise manufacturing machine performance. I am keen to work with engineers across the college as well as other disciplines such as environmental and bio-scientists, medical professionals and chemists.
Dr Rair Macedo, James Watt School of Engineering
'Putting a Spin on Electronics'
I am a Leverhulme Early Career Research Fellow/Lecturer in Electrodynamics and Spin Electronics and the Electronics and Nanoscale Division of the James Watt School of Engineering. I am mostly interested in how to modify materials properties—or build novel materials altogether—to manipulate electromagnetic waves. This is, in fact, the basis for how invisibility cloaks have been developed in the past few years! While this is a very whimsical application of novel materials, the same principles have also been used to enable technologies such as 5G, self-driving cars and even lenses with unlimited resolution.
In my research I have been particularly interested in manipulating electromagnetic waves with magnets, like those stuck to your fridge door but much, much smaller, and more recently I have been investigating how these can be used to aid information processing – either in our very own computers or even in the next generation i.e. quantum or neuromorphic computers.

'To see or not to see: X-ray Imaging in Science'
My research focuses on using x-ray computed tomography to image and capture physical and chemical changes in geo-materials, at the micro-scale. This technique allows to capture any change in the microscale in 4D (3 spatial dimensions and time) without physically destroying the sample. In particular, I conduct 4D experiments, in which rocks are exposed to changes in stress or fluid content and look at the response of the internal microstructure over time. I will show you some case studies in which XCT proves to be a very powerful analysing tool, to demonstrate that it can be integrated in many other research fields.
