Research

The goal of our research group is to gain new insight and understanding of chemical and physical change of molecules upon the interaction with photons and electrons. These changes underpin many processes is science and technology. For photon-driven chemistry, our interest ranges from photoactive proteins and DNA to atmospheric chemistry. For electron-driven chemistry, our interest ranges from electron transport chains in nature to electron capture within dense molecular cloud in the interstellar medium. We have developed novel methods that we exploit to access new information about the dynamics that dictate photon- or electron-driven chemistry, with a view to fully understand basic mechanistic details. Some highlights of our work include: the observation of electrons at the water/air interface (1), the first real-time measurement an electron-molecule reaction (2), the simultaneous probing of electronic and nuclear dynamics along a reaction coordinate (3); new insight into the role of non-valence states in anions (4); and the role of solvation in driving electron capture (5).
