      Associate professor at the Department of Chemical and Environmental Engineering of the University of Zaragoza (Spain), and researcher at the Thermochemical Process Group (GPT) of the Arag\u00f3n Institute of Engineering Research (I3A) of the University of Zaragoza (Spain).<\/p>\n

      My research interests are in the fields of high temperature chemistry, chemical kinetic modeling, and formation and destruction of air pollutants (nitrogen oxides, sulfur compounds, \u2026) in energetic and industrial processes\/applications.<\/p>\n

      BIOGRAPHY<\/strong><\/p>\n

      I graduated with a Master in Chemical Engineering from the University of Zaragoza (Spain) and in 2013 I got the degree of PhD in Chemical Engineering at the same university. As part of this investigation, in January-April 2011, I made a short term collaboration at the (Combustion Harmful Emission Control) CHEC group of the Technical University of Denmark. My research activities were related to hydrocarbon conversion in presence of different gaseous compounds that can be typically present in atmospheres with recycled flue gas (RFG), such as CO2<\/sub>, NOx\u00a0<\/sub>or SO2<\/sub>, to provide of the necessary experimental data both to get
      \ninsight into the phenomena controlling the process and to improve and update a gas-phase combustion scheme in relation to different reaction environments.<\/p>\n

      In 2015- 2017 I worked as a post-doctoral researcher at the Instituto de Carboqu\u00edmica (ICB) of the Spanish National Research Council (CSIC), with a research Grant funded by the Spanish Government.
      \nDuring this time my research activities were focused on the development and optimization of oxygen carriers for the Chemical Looping Combustion process.\u00a0 In June-September 2016 I made a short term collaboration at the Department of Mechanical Engineering (DEM) of the Technical University of Lisbon (Portugal), to study the influence of the presence of metals on the combustion of biomass.<\/p>\n

      Since 2017, I am a researcher at the Thermochemical Process Group (GPT) of the Arag\u00f3n Institute of Engineering Research (I3A) of the University of Zaragoza (Spain), performing fundamental studies related to the formation and destruction of main pollutants in thermo-chemical processes.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>
