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, Head of the School of Geography and the Environment, Co-Director of the EPSRC Centre for Doctoral Training in Science and Engineering in Art, Heritage and Archaeology, and Honorary Professor at University College London. She obtained an MA in Geography from the University of Cambridge, and a DPhil 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 the 2015 Ralph Alger Bagnold Medal from the European Geosciences Union for her role in establishing the field of biogeomorphology.
Heather was Chair of the British Society for Geomorphology from 2012 to 2014, and is currently a member of the Executive Committee of the International Association of Geomorphologists. From 2008 to 2011, she was Vice-President (Expeditions and Fieldwork) of the Royal Geographical Society with IBG. She was on the advisory panel of the £6.5 million AHRC/EPSRC Science and Heritage Programme from 2008-2012, 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.
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, NW China as well as many places within the UK.
Examples of areas where geomorphology can contribute to the understanding and conservation of cultural and natural heritage. a) Rock art on sandstone in Libya, and b) Sandstone peak forest, Zhangjiajie, China.

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 her 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, and the Equotip hardness tester. 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.
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, Historic England, the Royal Society and NASA.
Selected Research Projects
Prof. Viles was Director of Undergraduate Studies from 2008-2011, during which time the department completely revised its undergraduate course. She contributes to the 'Geomorphology' lecture course of the 'Earth System Processes' core course for Prelims, as well as to the Geographical Research course in the Final Honour School. She also convenes the 'Heritage Science and Conservation' Option and teaches on the 'Desert Landscapes and Dynamics' option.
Heather welcomes applications from students wishing to undertake graduate research in any aspect of biogeomorphology and heritage conservation.
