Siân Dutton is a Professor in Physics and Solid State Chemistry at the Cavendish Laboratory in the University of Cambridge and Director of the Winton Programme for the Physics of Sustainability. Siân completed her DPhil., in the on the ‘Synthesis and Characterisation of Mixed Metal Oxides’ under the supervision of Prof. Peter Battle. She then moved to Princeton University for postdoctoral work with Prof. Bob Cava on geometrically frustrated magnets. Since 2012 Siân has been based at the Cavendish Laboratory first as a Winton Advanced Research Fellow, and subsequently as a University Lecturer (2015) and Reader (2018). Her multidisciplinary research group explores the relationships between composition, structure, and physical properties with a focus on energy materials, including materials for rechargeable batteries, hybrid perovskites and low temperature magnetocalorics.
