Research Interests

I am interested in developing new and better ways to turn waste such as CO2 into useful fuels using renewable energy to address the grand challenge of climate change. In particular, I am interested in using the best parts of nature such as enzymes which can perform these reaction with unprecedented efficiency in combination with state-of-the-art materials that can effectively transfer energy to enzymes to allow them to operate at their best.

I use a wide range of experimental and computational techniques such as electrochemistry, multiple spectroscopic techniques, quartz crystal microbalance measurements and finite element modelling to understand how to develop better systems. Enzymes immobilised on electrodes are highly complex systems, which exist in an environment that is very different to bulk solution that can help (but also hinder) the performance of these systems. Understanding this environment is not straightforward, with multiple factors affecting their response and therefore only by combining multiple techniques can we begin to understand how to improve their performance. Using these techniques we can develop new materials and methods to improve the interaction between enzymes and the electrode, and also optimise their local solution environment through nanoconfinement effects to make the system perform at its best.

Also, I am interested in using enzymes as a model system to inspire the next generation of synthetic catalysts. Nature has already found solutions for many of the current challenges we face, and by learning from how nature solved these problems we can improve the performance of synthetic systems. We can also understand problems that synthetic catalysts may face as they improve, approaching the performance of enzymes.
