I grew up in Reading UK, 20 minutes by train from London. I went to Chiltern Edge Secondary School (11-16yrs) and Henley Sixth Form College (17-18yrs).
After two years of working and backpacking I went to The University of York, UK, to study undergraduate physics. My final year project was on the nucleation of freezing in supercooled water, supervised by Dr Richard Keesing. We scattered a laser through droplets of supercooled water to observed freezing as it was initiated by the application of an electric field.
In 2009 I was awarded a University Scholarship and started a PhD in glaciology in the Department of Geography at Sheffield University, supervised by Dr Felix Ng. I wrote a thesis entitled 'Modeling ice-dammed lake drainage' (pdf). I used mathematical models to study how water flows beneath glacier (see research section).
In 2013 I started as a Glacier Geophysicist at the British Antarctic Survey (BAS), Cambridge, UK. I was employed on a NERC-funded project led by Richard Hindmarsh. We used radar and mathematical models to study present-day and past ice flow in West Antarctica.
In March 2016 my wife and I moved from the UK to start my current position as Assistant Professor in the Department of Earth and Environmental Sciences, Columbia University, and the Lamont-Doherty Earth Observatory. I am continuing my research in Glaciology and teaching undergraduate and graduate students. I collaborate with members of the Polar Geophysics Group here at Lamont, and colleagues from Sheffield (e.g. J. Ely, S. Livingstone), BAS (e.g. A. Brisbourne, C. Martín) and elsewhere.
My research is focused on modelling and observing the flow of ice and water in ice sheets and glaciers.
During my PhD I studied the flow of water beneath glaciers and ice sheets through the development and analysis of mathematical models. I studied how ice-dammed lakes fill and drain beneath glaciers, showing how simple models can be used to predict approximately when lakes will drain, lakes can fill and drain chaotically and lakes affect the flow of glaciers through their impact on subglacial water pressures. I also observed and modelled large-scale surface drainage in East Antarctica.
My work at the British Antarctic Survey focused on using radar to constrain present and past ice flow in the Ronne Ice Shelf region of West Antarctica. We used a phase-sensitive radar system to measure an ice-dynamical phenomenon called the Raymond Effect.
In a paper from 2014, we used phase-sensitive radar and GPS to infer vertical and horizontal ice flow fields throughout the thickness of Korff Ice Rise, West Antarctica. We used these englacial flow fields with radar observations of internal layers within the ice rise to show that the flow of his part of the ice sheet underwent a reorganization around 2-3 kyr ago. Continued research into the history of the West Antarctic Ice Sheet is bringing together geophysical and sedimentological data with ice-sheet modelling to understand large-scale evolution of the ice sheet during the last few thousand years.
Throughout last year (2016) I, along with Lamont colleagues have been exploring the supraglacial (i.e. hydrology that goes on on the surface of ice) of Antarctica. This has been exciting because only a few studies have looked at water moving across the surface of Antarctica, but we hypothesize that surface water flow potentially has an important role to play in the future of the Antarctic Ice Sheet.
In two papers (here and here) recently published Nature, and summarized very nicely in the same issue (here), we showed water has been moving long distances onto and across many Antarctic Ice Shelves for many decades (possibly much longer).
Our observations of widespread supraglacial hydrology in Antarctica are interesting because as the continent warms, water could either move into areas where it can cause ice shelves to collapse, or it could evacuate water into the oceans as shown by one of our papers. The movie below, taken from a helicopter, shows a large water fall at the front of the Nansen Ice Shelf.

Field observations are an essential part of my research. I have been part of field expeditions to Southern Norway, Svalbard and Greenland, andled two expeditions in Antarctica.
During two austral summers I spent two months traveling across the West Antarctic Ice Sheet in a team of two (a mountaineer and I), conducting measurements of the ice flow using GPS and ice-penetrating radar.
During my first Antarctic field season, my field safety expert, Iain Rudkin, was also an amazing photographer. See some of Iain's photography from Antarctica and elsewhere here. Even after 12+ hours on a snow mobile, Iain somehow found the energy to get out of the tent and capture whatever nice clouds (not scenery as we were in the flat-white) that were outside. When we got back I put his timelapse photography together with some videos of my own and arranged them over a composition by Steve Massey, written while at the British research base, Rothera:
In April/May 2017 I spent four weeks traversing across the Greenland Ice Sheet as part of an NSF-funded project to investigate refreezing of meltwater in snow and firn. The project is led by Asa Rennermalm, Regine Hock and Marco Tedesco. More details soon. Meanwhile, here are some photos:
Also, here is a movie showing some pretty windy conditions that we encountered on the ice sheet.
I have been lucky to be involved with various outreach activities at Sheffield and BAS and this has continued at Lamont, with recent outreach events including the Women in STEM event at the Intrepid Air and Space Museum, the Earth-Sun Day at the American Museum of Natural History, Hudson River Sailing Community Sailing Club and Lycée Français de New York school.
At the American Museum of Natural History we played with 'glacier goo' to show visitors how glaciers flow. I captured the flow of this home-made 'viscous fluid' in time-lapse video using a smart phone:
