Ruth Lynden-Bell is Emeritus Professor of Condensed Matter Simulation. She obtained her degrees from the University of Cambridge. Her career tookk her to the University of Sussex where she was lecturer in Chemistry and then back to Cambridge. In 1995 she moved to QUB as a co-founder of the interdisciplinary Atomistic Simulation Group (now the Atomistic Simulation Centre). Since she retired she returned to the Department of Chemistry at Cambridge. Her current research interests include the investigation of solvation properties of ionic liquids using atomistic simulation and an attempt to understnad the properties of liquid water by comparing them to liquids made from modified water models. She was elected as an FRS in 2006 and was awarded a Leverhulme Emeritus Fellowship in 2004. She is an Emerita Fellow of New Hall, University of Cambridge and was an Associate of Newnham College. She has served on the editorial boards of Journal of Chemical Physics, Chemical Physics Letters and Science and was an editor of Molecular Physics from 1998 to 2003 and has been a member of Boards of Electors to Professorial positions in Sweden, the Republic of Ireland, and Oxford and Cambridge Universities.
