Jorge Ruiz Encinar received his PhD in Chemistry in 2001 from the University of Oviedo (Spain). After working as a postdoc at the CNRS “Laboratory of Analytical Bioinorganic and Environmental Chemistry (LCABIE)” in Pau (France), he returned to the University of Oviedo as a Ramón y Cajal Researcher (2004-2009). Since 2010 he holds an Associate Professor position at the same University. Additionally, he is Invited Professor at the University of Pau (France) since 2011 and he has taught a number of courses in companies and universities in different countries. In 2007, he was awarded with the “Young Chemist Prize” by the Spanish Royal Society of Chemistry. His main research interests are focused in mass spectrometry and stable isotope-based methods, mostly applied to environment, speciation and heteroatom-tagged proteomics, and the development and characterization of functionalized nanoparticles for bioanalytical applications. Jorge is co-author of about 100 peer-reviewed publications.
