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.


B.S., Mechanical Engineering, Louisiana Tech University, 2001

Ph.D., Materials Science and Engineering, University of Michigan, 2006


Picard's research utilizes advanced microscopy methods to study microstructural evolution and defect dynamics in functional materials. This research spans defect-property correlations in photovoltaics and fuel cells, materials processing by energy efficient manufacturing methods, and defect influence on memory storage and radiation damage behavior.


Transmission electron microscopy, scanning electron microscopy, electron channeling contrast imaging, electron backscatter diffraction, dislocation analysis in semiconducting materials and devices, structural analysis in nanoscale materials, atomic scale imaging/analysis of interfaces.
