Since 1991, Hugo Saldarriaga-Noreña has worked in the environmental pollution field, specifically in water purification. Later in 1995, I joined the University of Antioquia (Colombia), combining research with teaching, until 2001. In 2007, I joined the Center for Research and Assistance in Technology and Design of the State of Jalisco, Mexico, as a leading researcher in the area of air quality. Since 2012, I have been a full-time professor at the Autonomous University of the State of Morelos, Mexico. My research area is environmental chemistry, specifically oriented to the characterization of environmental matrices, through the application of high-performance liquid and gas chromatography, ICP mass spectrometry, nuclear magnetic resonance, and IR among others.
