Dr. Manin obtained his MSc degree in Mechanical Engineering and in Automotive and Transportation Systems in France, in 2006. He completed his PhD in Physics and Mechanical Engineering at the Polytechnic University of Valencia, Spain, in 2011. Dr. Manin has been working at Sandia National Laboratories since 2011, starting as a postdoctoral researcher. He now is a staff member in the Engine Combustion department. Over the course of his scientific career, he has been the advanced diagnostics lead at Artium Technologies, as well as an assistant professor at Hiroshima University, Japan, and at the Polytechnic University of Valencia. Dr. Manin has gained broad experience in fluid mechanics, thermodynamics, laser and optical diagnostics. He has been involved in many national and international research projects and has published more than seventy papers, either in scientific journals or at international conferences.
