Professor Stephen Parker FRSC (UBath) has an international reputation in the simulation of oxides and minerals and their interfaces. He has published >290 publications (h-index=49), was computational geochemistry theme leader for the Goldschmidt conference (Montreal, 2012) and a session coordinator at the ACS Spring Meeting (Dallas, 2014). Parker has developed computational software, particularly to model free energies of polar solids, used by groups worldwide. He has served on the J. Materials Chemistry Editorial Board, chaired the RSC Solid State Group, is Chair/PI of the EPSRC’s Collaborative Computational Project (CCP5) and has held visiting Professorships at Université Pierre et Marie Curie, Paris and at EPFL, Lausanne. His current studies include work on energy and nuclear materials, ceramic meta-materials and pollutant remediation, with 5 current EPSRC grants (including Co-I on EP/K016288 “Energy materials: Computational solutions”). He is the modelling of thermoelectric materials theme leader in the EPSRC Thermoelectric Network.
