My travel blog: Travels through geomorphology.
Research interest: Within the Global Change research group, I am part of the Land Surface Dynamics research group (FOLLOW US ON TWITTER: http://twitter.com/edinlandsurf). 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 the release and transfer of sediment can also help retrieving past tectonic and climatic signals in the geological archive (stratigraphy), as well as mitigating risks in sedimentary basins. The risks I am particularly interested in at the moment include flooding risk from in-channel sediment aggradation (e.g., response of Himalayan rivers to the recent Nepal 2015 earthquakes), and siltation and heavy metal pollution (e.g., new project on the environmental impact of nickel mining in the Philippines).

APPLY FOR A PHD PROJECT IN GEOSCIENCES. Deadline has passed…
To apply for a PhD or to browse the PhD projects available through the new E4 “Edinburgh Earth, Ecology and Environment” Doctoral Training Partnership funded by the NERC: https://www.ed.ac.uk/e4-dtp. Please check the deadlines and eligibility before contacting a potential supervisor (most of these projects are available only to UK students or students who have spent the last three years in the UK).
– LSDTopoTools Package
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!

A nice taster of Scotland and its amazing geology and landscapes (to me, this is one of the most beautiful places in the world): http://www.youtube.com/watch?v=Xe12VVXh93A&feature=youtu.be.
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…
INFLUENCE OF WOLVES ON RIVERS, beautifully illustrated and narrated: click HERE.
GRAVEL BED RIVERS CONFERENCE 8, September 2015:
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.
