Professor Picard obtained a B.S. in Mechanical Engineering from Louisiana Tech University in 2001 and a Ph.D. in Materials Science and Engineering from the University of Michigan in 2006. During his graduate career, he was a Microsystems Engineering and Science Applications Fellow at Sandia National Laboratories where he researched focused ion beam applications as well as pulsed laser ignition phenomenon in energetic thin films. Following his doctoral research on materials modifications by femtosecond lasers, he was a postdoctoral research associate at the U.S. Naval Research Lab (NRL), where he conducted electron microscopy studies of GaN devices, SiC thin films, and metal-oxide nanowires. He was subsequently hired as a staff scientist at NRL to carry out electron microscopy studies of metal alloy surfaces and magnetic metal-oxide thin films. He joined the faculty at Carnegie Mellon University in 2009.

Manipulating matter at the atomic scale is critical for engineering new materials and devices. Energetic beams offer many routes for stimulating structural transformations in materials as well as characterizing materials at the nanoscale. My research group develops and applies methods for using energetic beams (electron, ion and photon beams) in order to process and characterize materials at small length scales. This research includes novel structural characterization methods by microscopy (ion/electron channeling), nanoscale analysis of material structural transformations under applied electrical/thermal loads via in situ electron microscopy, and understanding laser-based thermo-mechanical processing in material surfaces. Furthermore, we seek to understand how certain aspects of local atomic structure in materials (strain, defects, phase transformations) influence electronic, thermal and mechanical properties.
