Research in the Weller group is based upon synthetic organometallic chemistry and catalysis, and in particular the generation and stabilisation of transition metal complexes with a low coordination number. These complexes often show very interesting, and novel, structures that display C–H, B–H and C–C bonding modes (via agostic or sigma interactions). Not only are we interested in the fundamentals of synthesis, bonding and structure of these complexes, but we also have a focus on their use and development in challenging catalytic bond transformations, such as C–H, B–H and C–C activation for the synthesis platform chemicals, new materials or fine chemicals. Collaborations with synthetic organic chemists (Professor Michael Willis, Oxford), computational chemists (Professor Stuart Macgregor, Heriot–Watt), experts in the study of mechanism using kinetics (Professor Guy Lloyd–Jones, Edinburgh) and novel analytical techniques (Professor J. S. McIndoe, University of Victoria), and Inorganic Materials Chemists (Professor Ian Manners, University of Victoria) also lead to a deeper understanding of structures and reactivity and applications of many of the new complexes and catalytic systems discovered.
Andrew Weller is a Professor of Chemistry at the University of York, moving with his group in January 2020. Prior to this position he was Professor of Chemistry at the University of Oxford, and a fellow of Magdalen College. He moved to Oxford in 2007, after starting his independent career at the University Bath in 1999 as a Royal Society University Research Fellow, promoted to Reader in 2004.
He completed his first degree at the University of Warwick, a PhD at Bristol (advised by Dr John Jeffery), and PDRA positions at Heriot–Watt (Professor Alan Welch) and Notre Dame (Professor Tom Fehlner).
Weller was the recipient of the inaugural Dalton Transactions European Lectureship award 2008. He was a 2013/14 Peter Wall Institute for Advanced Studies Visiting Scholar, UBC, Canada; in 2015 the Howard Fellow, University New South Wales, Australia, a visiting Professor at the University of Perugia, Italy and a Vielberth Fellowship at the University of Regensburg (2016). He is a currently holder of an EPSRC Established Career Fellowship (2015–2021) and was recipient of the Royal Society of Chemistry Frankland award in 2016. While at Oxford he was co–director of the recently funded EPSRC CDT in Inorganic Synthesis for Future Manufacturing (OxICFM).
