Natalia E. Fonseca González. Mechanical Engineer with PhD.in Thermal and Fluid Dynamic Engineering by UPM. Professor at the Department of Energy and Fuels at Energy and Mining School of the Universidad Politécnica de Madrid (UPM) since September 2011.

She has carried out the research activity in the field of determining the environmental impact of vehicles equipped with internal combustion engines since 2007 with emphasis on measuring emissions from vehicles with on-board emissions measurement systems, a subject on which she did the doctoral thesis: Aspects of the instantaneous dynamic measurement of engine emissions. Application to the development of a portable equipment and a methodology for studies of contamination of vehicles in real traffic. defended on December 20, 2012.

Since 2014, her research activity has been carried out at INSIA- University Institute of Automobile Research of the UPM in the lines of research related to the environmental impact of vehicles and internal combustion engines and the use of biofuels. Since August 2022, her research activity has been carried out at the EU Joint Research Centre-Ispra, as a visiting scientist, working on validation of HD laboratory and PEMS test procedure for HD H2 ICE H2-ICE and develop Proposal for the amendment of UN Regulation 49.

She has made several scientific publications in JCR journals and various presentations at prestigious national and international congresses. The most relevant ones on the study of episodes of high NOx emissions and studies about energy efficiency and emissions of bus and passenger cars.

The teaching activity has been carried out mainly in the areas of thermal machines and engines, teaching subjects such as Thermal Machines and Thermal Energy Efficiency at the bachelor's, master's and PhD level.
