José Carlos Jiménez Sáez was born in 1968. He received the degree of “Licenciado” on Physics (Specialty of Electronics and Material Physics) in 1991. In that year, Mr. Jiménez was designated lecturer of the Polytechnic University of Madrid in the Aeronautical School. In 2002, he received the PhD degree on Physics. His Thesis entitled “Analysis of Metallic Interfaces and their Modifications by Ionic Bombardment” received the “cum laude” distinction. In 2003, Mr. Jiménez became Honorific Collaborator at the Department of Applied Physics III of the Complutense University of Madrid. In 2008 he was promoted to full academic lecturer at the Department of Physics and Chemistry applied to Engineering of the Polytechnic University of Madrid. Dr. Jiménez is expert in Monte Carlo and Molecular Dynamics Simulation of radiation-matter interaction processes and material mechanical characterization processes, especially in the field of solid state device fabrication technologies. He is presently collaborating with the Department of Structure of Matter, Thermic Physics and Electronic in the simulation and modeling of novel solid state devices based on nanotechnology. His present lines of work include the study of thin-film growth and compound material characterization both by molecular dynamics simulation.
