Carlos Hernández-García
Photonics and Laser Applications Group


PhD in Physics (January 2013). Currently working as a Marie-Curie post-doctoral fellow at University of Salamanca (Spain), in the Research Group in Photonics and Laser Applications (ALF-USAL), with Prof. Luis Plaja. During the last two years, and within the Marie Curie fellowship, I conducted postdoctorate research at JILA, University of Colorado at Boulder, in the AMO theory group of Andreas Becker and Agnieszka Jaron-Becker, also in collaboration with the experimental group of Henry Kapteyn and Margaret Murnane.

Fields of interest: Laser-matter Interaction, Ultrafast Phenomena, Nonlinear Optics, High-order Harmonic Generation and Propagation, Attosecond and Zeptosecond Physics,  Orbital and Spin Angular Momentum, among others.
