One of the most pressing scientific problems today is understanding climate change and being able to accurately predict its impact. My research focuses on ice sheet dynamics, specifically on ice sheet interactions with the atmosphere and oceans. The research spans scales, from whole glaciers and ice sheets to micro-scale process studies and observations in boreholes. My Lab in Cambridge is at the forefront of its field and our research is novel and wide-ranging. One strand of the Lab is developing observational understanding of Earth's glaciated environment using autonomous radar systems, drones, GNSS, seismology and records from boreholes drilled through 1-km-thick ice to the base of fast-flowing glaciers. Another strand integrates those observations as constraints for 3D numerical models, thereby making predictions of glacial changes in the future more accurate.

My research in Greenland (RESPONDER) is currently funded by the European Research Council and the European Union's Horizon 2020 research and innovation programme. My Antarctic research is supported by one of eight large-scope science grants awarded in the International Thwaites Glacier Collaboration, which is co-funded by NERC and the National Science Foundation in USA.

The Christoffersen Lab in the Scott Polar Research Institute currently includes Dr Marion Bougamont (Senior Researcher), Dr Charlotte ("Charlie") Schoonman (postdoc), Dr Tun Jan ("TJ") Young (postdoc), Tom Chudley (PhD), Samuel Cook (PhD), Rob Law (PhD) and Isabel Hagen (MPhil).

Graduate students

Graduate students are an integral part of my group, and I believe that one of the most fruitful components of graduate teaching is the integration of students in my own research. The opportunities for student-led research in my group are wide-ranging and often inter-disciplinary in scope.

Tom Chudley is using unmanned aerial systems, i.e. drones to investigate hydrological networks, calving and rapid lake drainage on Store Glacier in Greenland. Samuel Cook is using the Elmer/ICE finite element model to investigate basal hydrological systems and how hydrology influences ice flow and iceberg calving through plume-induced frontal melting at Store Glacier. Robert Law is using fibre-optic sensing in boreholes to investigate heat flow and thermal conditions of ice.

Past students in my Lab include Tun Jan "TJ" Young who submitted his thesis ('Investigating fast flow and thermal regimes of the Greenland Ice Sheet') on the basis of high-precision radio-echo sounding data collected on Store Glacier during five successive polar expeditions. Craig Stewart, who received the Scott Centenary Scholarship, based his thesis ('Ice-ocean interactions beneath the north-western Ross Ice Shelf, Antarctica') on data collected with a mooring installed on the Ross Ice Shelf. Dr Joe Todd based his thesis ('A 3D Full Stokes calving model for Store Glacier, Greenland') on numerical modelling with the Elmer/ICE finite element package. Dr Narelle Baker (now van der Wel) based her thesis ('The influence of subglacial hydrology on the flow of West Antarctic ice streams') on the integration of hydrology and ice flow in an ice sheet model and Dr Martin O'Leary based his thesis (' Frontal processes on tidewater glaciers') on a study of buoyancy-driven meltwater plumes.

I am always happy to discuss project ideas and funding opportunities by e-mail, skype or telephone.

MPhil in Polar Studies

I usually supervise one or two students on the MPhil in Polar Studies per year. This programme differs from many other Masters programmes in that students are encouraged to develop independent research projects from which they can write a scientific paper. Since 20007, I have supervised 16 MPhil students, eleven of whom graduated with Distinction and many continued as PhD students in Cambridge or another top university in the UK or abroad.
