Welcome to our group website!

Oxidation-reduction (redox) reactions underpin innumerable chemical reactions - and much of the chemistry of life! I am fascinated by how oxidation-state changes govern respiration and photosynthesis and how nature has fine-tuned the redox properties of its many intricate molecular machines. Redox reactions often involve transition metal ions and in the group we are investigating the properties, structure and bonding of transition-metal centres in both biological and synthetic molecular machines.

Many redox reactions proceed via radical intermediates and these are, perhaps luckily, often located in mechanistically key locations. In the lab, we use
electron paramagnetic resonance (EPR) spectroscopy as a powerful method for obtaining detailed information on the structure and bonding these ubiquitous spin centres. Electrochemistry on the other hand, in particular film electrochemistry, provides insight into the reactions carried out by molecular machines. These (bio)physical methods are supplemented by biochemical and synthetic methods.
