Philippe Lours is Professor at Mines Albi. He conducts research and teaching at the University of Toulouse - Mines Albi since 1995. He is also an invited professor at ISAE - SupAéro (Institut Supérieur de l’Aéronautique et de l’Espace - Supaéro), at the University Paul Sabatier Toulouse, at the University of Transports and Communications Hanoi (Vietnam). He has been lecturing in several universities over the world, including the University of California at Berkeley (1990), Ecole Polytechnique de Montréal (1993), Université Joseph Fourier Grenoble (1998), Toyohashi University of Technology - Japan (2002), Dalian Maritime University - China (2004), Universitatea Dunarea de Jos - Galati Romania (2000-2005), the University of Science & Technology Hanoi - USTH  (2013), the Civil Aviation University of China - Tianjin (2013).

Graduated in Materials Science & Engineering at INSA (Institut National des Sciences Appliquées) and in Solid State Physics (1986), Philippe Lours defended his doctoral thesis on the plasticity of single crystal nickel based superalloys investigated by In Situ Transmission Electron Microscopy in 1989. After a postdoctoral fellowhip at the Lawrence Berkeley Lab. (Berkeley, USA) where he further specialised in Transmission Electron Microscopy including High Resolution and High Voltage TEM, he has held several positions of R & D engineer, process engineer and project engineer in the metal alloys industry in Toulouse, France (sputtering targets) and Montreal, Québec-Canada (shape memory alloys).

Full Professor at Mines Albi where he has founded the Master program "Materials for Aeronautics & Space" in 2003, he is now head of the new Master "Advanced Materials & Mechanical Engineering". Author of 50 articles in international journals with peer review and book chapter, Philippe Lours participated to more than 70 national and international conferences. He is former head of the research team PUMMA (Enginering Properties & Microstructure of Advanced Materials) at Institut Clément Ader. Director or co-director of fourteen PhD students, his research focusses on the relationship between the microstructure and the engineering properties of metallic materials and coatings with a particular attention on high temperature materials for aerospace applications (superalloys and thermal barrier coatings). HDR of the National Polytechnic Institute of Toulouse, Philippe Lours is a member of the management team of the PhD School "Aeronautics & Astronautics" and was awarded the rank of "chevalier dans l’ordre des palmes académiques" in 2009.
