Heather Viles is a geographer with major interests in geomorphology and heritage science. Much of her research focuses on the application of science to heritage conservation. She is currently Professor of Biogeomorphology and Heritage Conservation, having previously been a University Lecturer and then Reader in the University of Oxford. She is a Fellow of Worcester College, and a lecturer at St Hilda's College. She is also an Honorary Research Fellow in the School of Geography, Archaeology and Environmental Studies, University of the Witwatersrand. She obtained an MA in Geography from the University of Cambridge, and a D.Phil. from the University of Oxford. Her D.Phil. thesis focused on the role of microorganisms in weathering limestone and was based on fieldwork on Aldabra Atoll in the Seychelles. After completing her D.Phil. she undertook post-doctoral research on the contribution of acid rain to the deterioration of English cathedrals. Heather was awarded a 650th anniversary Gold Medal, by Charles University, Prague (1998) for her contributions to international research collaboration in geomorphology.
Over the years, Heather has carried out field-based research in NW Australia, South Africa, Namibia, Washington State, the Atacama Desert in Chile, South Germany, the Sahara Desert in Libya, as well as many places within the UK.
Currently, Heather is Deputy Chair of the British Society for Geomorphology, and will become Chair for a two year term starting in 2012. From 2008 to 2011, she was Vice-President (Expeditions and Fieldwork) of the Royal Geographical Society with IBG. She sits on the advisory panel of the £6.5 million AHRC/EPSRC Science and Heritage Programme, and was also a member of the National Heritage Science Strategy steering group co-ordinated by English Heritage and charged with developing a UK-wide Heritage Science Strategy which will shape UK-wide policy over the next 25 years. Heather also represents the University of Oxford as a trustee of the Oxford Preservation Trust. She is also an Associate Researcher at the Oxford Biodiversity Institute.
Recently, Heather has been asked to give keynote lectures at the German Geographical Congress in 2009 (where she talked about the role of physical geographers in conservation), and the 2011 Binghamton Symposium (where she will discuss the importance of microorganisms to geomorphology). She gave one of the Nigel Seeley Memorial lectures at the Bartlett School for Architecture (on greening the conservation of ruins). She is also giving (with Dr Tom Spencer, University of Cambridge) an invited talk to the 2011 Lyell Symposium at the Geological Society of London on island geomorphology. In Autumn 2011 she is taking up a three month Conservation Guest Scholarship at the Getty Conservation Institute, Los Angeles.
Prof. Viles' research is highly interdisciplinary and involves studies at the interface of geomorphology with ecology, engineering geology, environmental chemistry and materials conservation. In recent years she has focussed on three specific themes in my research, namely:
- Biological contributions to geomorphology;
- Weathering, geomorphology and landscape evolution in extreme environments (hyper-arid, coastal, cold, and Mars); and
- Building stone decay and conservation.
She maintains a strong interest in developing and applying novel techniques and ideas to the study of these themes, including 2D resistivity surveys using Geotom equipment (with Prof. Dr Oliver Sass, University of Graz), and the Equotip hardness tester (as discussed in this recent paper). She has recently set up the Conserving Stone Heritage website which showcases some of the methods used. Heather also has a strong interest in the practical applications of 'green' methods of conserving cultural heritage (using plants, animals and microorganism communities) and linking this to biodiversity conservation.
She currently collaborates with many colleagues around the world, including Prof. Andy Whiteley (CEH, microbiology); Prof. Bernie Smith (Queen's University Belfast, geomorphology); Prof. Stefan Grab (Witwatersrand, geomorphology), Dr Phillip Fletcher (British Museum; materials conservation); Dr Mary Bourke (Planetary Science Institute, Tucson, Arizona; planetary geomorphology). Heather runs the Oxford Rock Breakdown Laboratory Group (OxRBL) which has extensive laboratory facilities and a field test site at Wytham Woods near Oxford.
In recent years her research has been funded by EPSRC, AHRC, the Leverhulme Trust, University of Oxford Fell Fund, English Heritage and NASA.
