Research interest: Within the Global Change research group, I am part of the Land Surface Dynamics research group (FOLLOW US ON TWITTER: I combine the analysis of real landscapes (collection of field data, topographic analysis) with numerical modelling and experimental studies to constrain the relationships between tectonics, erosion and the development of topography. My current research focuses on understanding the coupling between hillslopes and rivers, characterizing and quantifying fluvial erosion and transport processes in mountain rivers and defining the role that sediments play in modulating fluvial erosion rates. My work can help extracting tectonic information from topography, with implication for assessing seismic and landslide hazard. Understanding sediment dynamics can also help retrieving past tectonic and climatic signals in the geological archive (stratigraphy) as well as mitigating flooding risk in sedimentary basins where in-channel sediment aggradation can result in increased flooding and avulsion risk. I am particularly interested in the sedimentary response of Himalayan rivers to the recent Nepal 2015 earthquakes, which is likely to cause a significant increase in flooding risk in the Ganga Plain (home of around one billion inhabitants) in the years to come.

PhD students:

- LAURA QUICK is investigating sediment dynamics at the front of the Himalayas, from Neogene to modern times.
- BORIS GAILLETON is looking at "post-orogenic evolution of the Carpathian mountain range".
- LIZZIE DINGLE is constraining "River dynamics in the Himalayan foreland basin". Check out Lizzie's BLOG.

- EMMA GRAF is joining our Himalaya research team to constrain sediment transfer from source to sink.

Past students:

- Dr FIONA CLUBB has been "Modelling the competition between climatic and geologic control on the development of landscapes". She is currently doing a short postdoc in Minnesota before moving to Potsdam for a longer one.
- Dr EDWIN BAYNES has been "Quantifying bedrock erosion during extreme flood events" in Iceland. Ed is now a Marie Curie research fellow at the University of Rennes, France (sacrebleu!)
See Ed's Icelandic videos: Iceland PhD fieldwork June 2012 ----- Iceland PhD fieldwork part 2, August 2012 ----- A field work saga, Iceland 2013 ----- Iceland: a research story.
Listen to Ed talking about his project on Radio New Zealand National (the interview covers many aspects of his project, it's very nice - don't get distracted by the opening sentence!): Podcast.
- Dr MARTIN HURST has been "Using hillslopes as recording devices to investigate how landscapes adjust to tectonic changes". He is now Lecturer at the University of Glasgow.



The Land Surface Dynamics group has released a package to do topographic analyses, including the "chi-analysis" (see Perron and Royden, 2013) which has the advantage of not being sensitive to the noise inherent to topographic data (i.e., slope-area data tend to be very noisy because of steps in river profiles). The paper presenting the tool and its application is available: click here. Simon Mudd and his team of hackers have designed a book in addition to the package. Both can be found on Github: the book and the package. Feel free to try it and give some feedback!

SteepestDescent talk, 3rd May 2014:

SteepestDescent is "a day of focused interactions and networking between people interested in surface dynamics" happening on the Saturday after the EGU conference, in the spirit of the Gilbert Club following the AGU conference. If you are interested in my talk: SteepestDescent.ppt.


Really cool: the Geological Society's 100 great geosites: click HERE for the interactive map and exciting pictures.

I am a bit disappointed the Helmsdale Boulder beds are not featured...


OPEN ACCESS JOURNAL - Geo: Geography and Environment.

The Royal Geographical Society (with the Institute of British Geographers) is pleased to announce the launch of a new open access journal. The journal is now open to submission of original work in the fields of physical and human geography, as well as work combining both disciplines. More information can be found here: Geo.


INFLUENCE OF WOLVES ON RIVERS, beautifully illustrated and narrated: click HERE



The Gravel Bed Rivers conference 8 just took place in Kyoto and Takayama, Japan, on the theme "Gravel bed rivers and disasters". The conference takes place every five years and leads to the production of a book presenting the work shown in the talks. You can find the list of talks (and therefore, incidentally, book chapters) there: GBR8 Programme. The talks have been recorded and can be seen there: GBR8 talks (my talk is in session 7, starting at ~30 minutes). The book is now available here. In the meantime, if you are interested in my talk on "Linkage between sediment transport and supply in mountain rivers", here is the ppt: Part 1 and Part 2.
