My name is Leticia Miguens, Bsc in Chemistry-Environmental role from the University of A Coruña. After working for three years as a laboratory technician in the cosmogenic laboratory at SUERC (Glasgow), I am currently working at the National Research Center on Human Evolution in Burgos (Spain). Since 2009 I am a lab technician for the Geology laboratory. I have developed some techniques such as particle analysis by diffraction laser (Coulter) and other geological and sedimentological analysis of samples that come from different archeological sites. I coordinate the work of the laboratory's human team and deal with administrative issues. On a daily basis I work along with different labs, technicians and scientists, providing proposals and solutions to their questions.
