Daniel Carrizo, research scientist at the Centro de Astrobiología. PhD in Environmental Analytical Chemistry (2007) (Barcelona, Spain) and a B.Sc. in Biological Sciences (1997) (Uruguay). I have a multidisciplinary background (biogeochemistry, analytical and environmental chemistry) with extensive laboratory and field experience (Arctic, Atlantic, Antarctica, Atacama Desert, etc.). I have expertise in the development and application of analytical techniques (GC-MS, HPLC, GC-IRMS, IR, Raman) for the investigation the fate, cycling and taphonomic process of organic compounds and stable isotopes in the environment. From 2007 to 2016, I had five post-doctoral contracts: 1) The University of Newcastle (Australia, 2007-2008); 2) Stockholm University (Sweden, 2008-2011); 3) Universidade de Evora (Portugal, 2011-2012); 4) Zaragoza University, and 5) Queen´s University (UK, 2015-2016). From March 2016, I was granted with a Ramón y Cajal contract in the Centro de Astrobiología, to develop a line in “Biogeochemistry of Extreme Environments for Space Exploration”.
