Fiona's PhD has focused on the circular economy of critical metals
Why did you decide to undertake this project?
I am researching the application of bioleaching as a potential sustainable method for recovering technology-critical metals from waste materials, with a particular focus on Rare Earth elements. I am passionate about this topic as metals are essential for many of the technologies that will enable us to transition away from fossil fuels as we strive towards Net Zero. A sustainable and local supply of these metals will be important not only for social and environmental reasons (to reduce reliance on harmful mining practices exploiting people and the planet), but also for geopolitical security in a changing world.
What are your ambitions for the future?
I enjoy working alongside others who are motivated to make a difference in the world through innovative sustainable solutions to real-life problems. I’d love to stay working in the sustainable biotechnology space as a researcher, or work in the broader landscape supporting the translation of research to application. I am also interested in policy, especially after my PhD placement experience with the Scottish Science Advisory council which has opened my eyes to how science and research links into the bigger picture.
What excites you about your research?
I think that harnessing and enhancing the incredible natural capabilities of microbes through biotechnology offers great opportunities for a sustainable future that we have only just started to explore, and the complexities of the topic and near-endless possibilities are fascinating as a researcher. Engineering Biology has been highlighted as one of the five critical technologies by the UK Government, and I agree that it can be an incredibly powerful platform technology with a hugely diverse range of potential applications.
Where/what do you think the next innovation in IB will be?
It is very hard to predict with so much going on in the field. Feeding the world has to be high on the priority list, so I think some of the most transformative innovations could be achieved through engineering biology to create crops that are resilient to the effects of climate change, ensuring food security into the future. In the shorter term, the scale-up of alternative protein production, and sustainable bio-based replacements for traditionally fossil-based chemicals are both exciting opportunities.
What is an interesting fact about you / what do you enjoy doing away from your studies?
My passion outside of my studies is orienteering- a running-based navigation sport. Last year I took a break from my studies to represent Great Britain at the World Championships (hosted in Edinburgh), and also won a Gold medal in the relay at the World University Championships in Bulgaria. I enjoy the combination of the physical and mental challenge, and visiting places I would not have otherwise seen.
