Andrés Rivera was born in Santiago, Chile and received a degree in Geography from Universidad de Chile, where he is associated professor until today. He has worked in glaciology since 1988, when he studied glaciers on top of active volcanoes in southern Chile. Since then he has focused on glacier variation studies particularly in Patagonia, the Lake District and Central Chile. In 1997 he completed a Masters degree in Geography at Universidad de Chile, conducting a number of research activities in the Highlands of Northern Chile (Puna de Atacama). In 2004, Andrés received a PhD in Glaciology from the University of Bristol, England, where he worked with Jonathan Bamber at the Bristol Glaciology Centre. His thesis was related to the mass balance of the Southern Patagonian Icefield. Andrés has shown permanent interest of studying the Northern and Southern Patagonian Icefields, where he has conducted a number of fieldwork activities, and lately, surveys with airborne sensors, radars, and sonar. Andrés has also been actively involved in various glaciology research projects in Antarctica. He participated in several field campaigns to Patriot Hills (80ºS), more recently to the Antarctic Peninsula in collaboration with the Chilean Air Force and the British Antarctic Survey (Fleming Glacier, 69ºS) and to the glaciers in the Amundsen Sea area (75ºS) onboard a Chilean navy P3 airplane, from where airborne surveys were conducted in collaboration with NASA. He has done several over snow traverses in the interior of the Antarctic ice sheet in collaboration with the private company ALE and the Chilean Army, and more recently he has explored subglacial Lake Ellswroth and nearby glaciers (Union Glacier, 79ºS). Andrés is particularly interested in techniques and methods such satellite remote sensing, laser altimetry, GPS surveys, ice thickness measurements with radio echo sounder systems and measurements of glacier energy and mass balances. He has collaborated in many international research projects with Japanese, British, Swiss, German, Danish and North American researchers. Andrés is an elected member of the Council of the International Glaciology Society, and collaborates with many international journals
