My main research area throughout my career has been Cenozoic landscape evolution and denudation over thousands to millions of years, on both passive continental margins and in active mountain belts. The main techniques that my PhD students, post-docs and I currently use are cosmogenic nuclide analysis, various morphometric analyses, and, more recently, OSL analyses (with Professor David Sanderson at the Scottish Universities Environmental Research Centre [SUERC]); we are moving into the area of meteoric cosmogenic 10Be (led by the PhD work of Eric Portenga, and in collaboration with SUERC's Dr Dylan Rood). We have developed novel applications cosmogenic nuclide analysis, including using PDFs of single-grain cosmogenic 21Ne concentrations in sediments to infer catchment morphology and processes (with Professor Fin Stuart, SUERC), and in situ 14C in quartz (with Professor Gordon Cook, SUERC). It is clear that applications of all these analytical techniques are collaborative with SUERC. Recent funding for this research has come from NERC, the Scottish Funding Council and the European Commission.
Current work is focused on the ways in which bedrock rivers and the landscape respond to rock uplift. A major focus is using the glacio-isostatic rebound of northern Britain to test hypotheses concerning knickpoint retreat in response to rock uplift. We find that knickpoint retreat scales closely to catchment area (a surrogate for water and sediment discharge) and that this scaling is not influenced by rock type or structure. I am extending this work to examine knickpoint retreat in the semi-arid carbonate terrains of Mallorca, in collaboration with Dr Celso Garcia of the University of the Balearic Islands in Palma. Perhaps not unexpectedly, we are finding distinct differences between retreat rates in Scotland and Mallorca. We are not neglecting Scotland, however, and Julia Stockamp in her PhD work (co-supervised by Zhenhong Li in Newcastle, Glasgow's Jim Hansom, Ali Rennie of Scottish Natural Heritage [who are 50% funding the PhD], and myself) is using InSAR and differential GPS to assess rates of ongoing (modern) glacio-isostatic rebound in northern Britain.
Lithology is influential in situations of low stream power (i.e., low discharges and/or low stream gradients) such as in the post-orogenic settings of interior SE Australia. Knickpoints in such post-orogenic settings, driven by denudational isostatic rebound, readily propagate upstream until they encounter resistant lithologies, where the knickpoints 'stall'. In those situations, the catchment areas above the knickpoints become 'detached' from the base-level signal, meaning in turn that catchment relief must be increasing. Danile Peifer Bezerra, a new PhD student funded by Brazil's 'Science Without Borders' scheme, is examining such issues in the Quadrilátero Ferrífero region of Brazil.
I also have ongoing and now rapidly developing geoarchaeological interests. I have worked in Thailand and Cambodia with large archaeological teams, providing the landscape and environmental contexts for the archaeological findings. Eric Portenga's PhD work, jointly with Macquarie University in Sydney and SUERC, is using single-grain optically stimulated luminescence and meteoric 10Be analysis to assess the impact on landscape stability of 18th century Europeans' arrival in Australia. I am currently developing work on the geoarchaeology and chronology of lime-buring kilns in Scotland, looking to work with local agencies to expand on this area.
I am a geomorphologist. My PhD, on the evolution of the SE Australian high elevation passive continental margin, is from the School of Earth Sciences at Macquarie University in Sydney, Australia, which also awarded me a DSc in 2009. I came to Glasgow in 1998 to take up the Chair of Geography, after nine years at Monash University in Melbourne. For the last seven years in Melbourne, I was the Director of Monash's Graduate School of Environmental Science.
I was elected a Fellow of the Royal Society of Edinburgh in 2004, a Fellow of the Geological Society of America in 2011, and a Fellow of the British Society for Geomorphology in 2013.

Throughout my time in Glasgow, I have taught at all levels of the Earth Sciences and Geography degrees, and I continue to do so. I also teach one seminar per semester on 'Science and Natural History' in the Scottish Enlightenment course for Principia Consortium students from the US, run by the School of Critical Studies. I have several times been School Graduate Convener and I currently administer the School's new taught MSc in Aquatic Sciences.
