    Biography

    I am glaciologist and physical geographer who researches glaciers and ice sheets and polar landscapes. I work in the Arctic and the Antarctic where the impact of climate change is sustained and growing year after year. Understanding and tackling climate change and its impact are, to me, urgent tasks for scientists, policymakers, NGO’s, journalists, responsible private corporations, and people in general. My research focuses on glacier dynamics and glaciers’ interaction with the atmosphere and the ocean. My work in the Arctic includes investigations of Store Glacier in west Greenland, with the aim of understanding why it discharges 30 million cubic metres of ice into the sea every day. To resolve this problem, I use images collected by satellites and unmanned aircraft (UAV), data from sensors and instruments installed at the surface and the bottom of the glacier, and computer models. My Antarctic research focuses Pine Island Glacier and the stability of the West Antarctic Ice Sheet, which is losing mass and therefore becoming precariously unstable as a consequence of climate change.
