Sam is a graduate student in Geomorphology and Earth Surface Process Modeling (Sections
). He is currently funded through a Marie Curie European Training Network (ETN) called SUBITOP:
Sam has an undergraduate degree in chemistry and a master’s in theoretical condensed matter physics, both from the University of Oxford. He worked as a high school teacher and private tutor before starting his PhD in the Earth and Planetary Sciences department at Harvard University. During his time at Harvard, Sam discovered geomorphology. Unable to pursue his interest — at the time, there wasn’t a geomorphologist on the faculty — Sam decided to leave Harvard and continue his studies at the GFZ under the supervision of Jean Braun, Niels Hovius and Jens Turowski.
Broadly, the subject of Sam’s research is the general problem of substrate controls on topography and erosion: how do the material properties of a landscape affect its shape? His particular focus is on the role that discontinuities — including rock fractures, lithological transitions and dykes — play in determining patterns of erosion and topography along rocky coastlines. In order to unravel these relationships, he has developed a method based on the wavelet transform that allows quantitative comparisions to be made between coastal topography and discontinuity data, as well as other data types. He has also developed a simple and inexpensive field method for the collection of such data, over a wide range of scales. Sam’s field site is in West Cornwall, UK.
