I am a climate geochemist interested in the response of ice on earth to climate change. My research group is centered around a laboratory specialized in extracting and analyzing cosmogenic nuclides from rocks, sediments, water and ice. These cosmogenic nuclides are monitors of exposure of the sample to open sky (and to bombardment of the sample surface by cosmic ray particles -neutrons and myons- that produce characteristic isotopes in the surfaces). These techniques have advanced our abilities to quantify earth surface processes in general, and are particularly powerful in the field of glacier and ice-sheet dynamics and their coupling to climate change.
Our main focus has become to improve our estimates of contributions to sea level rise by melting ice sheets and mountain glaciers, one of the most pressing questions of sciences and societies.
