Research Interests

His pioneering research in developing the Fe grain chemical fingerprinting technique has lead to the discovery of massive surges of glacial icebergs into the Arctic Ocean several times in the past corresponding to and perhaps matching in ice volume the well-documented Heinrich Events in the North Atlantic, the influence of the Arctic Oscillation on ice drift over the last 10,000 years and that it has both century-scale and millennial-scale cyclicity, and new insights into sediment entrainment and transport by sea ice in the Arctic.
