Awards

Wei Cai, an assistant professor of mechanical engineering at Stanford University, was honored with a 2004 Presidential Early Career Award for Scientists and Engineers (PECASE) for work he did while serving as an Ernest O. Lawrence Fellow at the Laboratory. The award was presented on June 13, 2005, by Presidential Science Adviser John Marburger in a White House ceremony. Cai was nominated for the award by the National Nuclear Security Administration’s Office of Defense Programs in recognition of his role in developing Livermore’s Parallel Dislocation Simulator, a supercomputing model that simulates the dynamics of crystals as they deform. Laboratory Director Michael Anastasio says Cai’s computational theory of dislocation dynamics “after many years has been able to unify dislocation physics and crystal plasticity in a new computational discipline.”
PECASE recognizes outstanding scientists and engineers who show exceptional potential for leadership at the frontiers of knowledge. The award is the highest honor bestowed by the U.S. government on scientists and engineers beginning their independent careers. Cai was one of 58 PECASE winners in 2004.

A team of researchers from Carnegie Mellon University, including Livermore researcher Bassem El-Dasher, received the 2005 Henry Marion Howe Medal from the American Society for Metals International. The award recognized the team’s paper “Statistically Representative Three-Dimensional Microstructures Based on Orthogonal Observation Sections,” which appeared in Metallurgical and Materials Transactions A.
Established in 1923, the Henry Marion Howe Medal recognizes the authors of the best paper published in the journal for a given year and volume. In the 2005 award-winning paper, the researchers reported on a method they developed for modeling a polycrystalline microstructure in three dimensions using only two perpendicular sides of the material.
El-Dasher, who was completing graduate school at Carnegie Mellon at the time, is now a postdoctoral researcher for the Yucca Mountain Project in Livermore’s Chemistry and Materials Science Directorate. Using techniques associated with his research at the university, he is characterizing the phases that can form over time in the outer barrier of nuclear waste packages.
