Dr Alexander Gentleman

Dr Alexander Gentleman is a College Lecturer in Natural Sciences at Magdalene.

Before arriving in Cambridge, I worked as a Senior College Lecturer in Physical Chemistry at Keble College, Oxford in addition to also holding Postdoctoral Research Associate positions in the research groups of Prof Stuart Mackenzie and Prof Claire Vallance in the Department of Chemistry at the University of Oxford from 2014-2019. I am a graduate of the University of Adelaide, Australia, where I received a B.Sc. degree majoring in both the chemistry of materials and theoretical physics in 2004, followed by a B.Sc. (Honours) degree in chemistry in 2005 and a PhD in Chemical Sciences in 2014.

Research Interests

My primary research interest involves developing new optical detection and spectroscopy methods for optofluidic microreactors based on hollow-core photonic crystal fibres in order to study novel hybrid photocatalytic systems. I also maintain research interests involving: (a) The development and optimisation of colourmetric assays for detecting common nutrients and pollutants in rivers and lakes for their evaluation within an optical microcavity sensor, (b) Investigating the photodissociation dynamics of gas-phase transition metal-containing molecules using the Velocity-Map Imaging (VMI) technique, and (c) using a combination of Infrared (IR) action spectroscopy and computational chemistry to investigate: (i) The structures of gas-phase metal ion-molecule complexes, (ii) the structures of gas-phase transition metal clusters and their small molecule complexes, and (iii) the IR-induced reactivity of small molecules adsorbed to transition metal cluster surfaces. In addition to these research topics, I also have an interest in: (a) High-resolution spectroscopy of small hydrocarbon molecules, and (b) the use of computational chemistry to aid in the elucidation of experimental observations in organic and inorganic reactions, e.g. the product selectivity of P450 enzymes, facile decarboxylation in organometallic reactions.
