Professor Yavari joined the School of Civil and Environmental Engineering at the Georgia Institute of Technology in January 2005. He received his B.S. in Civil Engineering from Sharif University of Technology, Tehran, Iran in 1997. He continued his studies at The George Washington University where he obtained an M.S. in Mechanical Engineering in 2000. He then moved to Pasadena, CA and obtained his Ph.D. in Mechanical Engineering (Applied Mechanics option with minor in Mathematics) from the California Institute of Technology in 2005. Professor Yavari is a Fellow of the Society of Engineering Science and a member of the American Academy of Mechanics.

Professor Yavari's interests are in developing systematic theories of discrete mechanics for crystalline solids with defects. Defects play a crucial role in determining the properties of materials. The development of atomistic methods including density functional theory, bond-order potentials and embedded atom potentials has enabled a detailed study of such defects. However, much of the work is numerical and often with ad hoc boundary/far-field conditions. Specifically, a systematic method for studying these discrete yet non-local problems is lacking. Design in small scales requires solving inverse problems and this is not possible with purely numerical techniques. From a mechanics point of view, defective crystals are modeled as discrete boundary-value problems. The challenging issues are extending the existing techniques from solid state physics for non-periodic systems, new developments in the theory of vector-valued partial difference equations, existence and uniqueness of solutions of discrete boundary-value problems and their symmetries, etc. The other efforts in this direction are understanding the geometric structure of discrete mechanics and its link with similar attempts in the physics and computational mechanics literatures and investigating the rigorous continuum limits of defective crystals

Stewart’s research is focused on experimental methods for characterized the response of structures to natural and manmade hazards. She has been involved with many blast, shock, impact and seismic experimental and computational programs. These including blast testing of steel structural columns, blast testing of steel stud wall systems, material testing for ultra high performance concrete for impulsive loads and seismic testing for Los Alamos National Laboratories. She has also conducted advanced finite element analysis for the World Trade Center 7 Collapse, AFRL Munitions Directorate small munitions program and programs supported by the Technical Support Working Group. Her design experience includes blast analysis for the Veterans Affairs and consulting projects for various companies.

Muhanna is an associate professor in the School of Civil and Environmental Engineering at Georgia Institute of Technology. He obtained his B.S. in Civil Engineering from the University of Damascus in 1972, and his M.S. and Ph.D. degrees in the area of Solid and Structural Mechanics in 1976 and 1979, respectively from the Higher Institute for Structure and Architecture, Sofia, Bulgaria. He joined the faculty at the University of Damascus, Syria in 1980, and has also served on the faculty at Case Western Reserve University, Ohio and the University of Maryland (1991-2000). Muhanna has won a number of international prizes, among them: the Aga Khan Award for Architecture, one of the most prestigious international architectural awards, for the his masonry shell system without steel reinforcement (1992); the Golden Prize of the World Intellectual Property Organization (WIPO), for the best displayed patent at the International Fair of Damascus (1988); and the Special Prize of the United Nations HABITAT (1989). Muhanna's research activity is in the general area of solid and structural mechanics that includes uncertainty modeling, structural reliability, computational reliability, shell theory, and optimization of masonry building materials in structural systems. This research activity has culminated in the development of the new methods for reliable engineering computing, establishment of the Center for Reliable Engineering Computing (REC), and hosting the bi-annual international NSF sponsored workshop on Reliable Engineering Computing since 2004.

Zhu's research focuses on the modeling and simulation of mechanical behavior of materials at the nano- to macroscale. Some of the scientific questions he is working to answer include understanding how materials fail due to the combined mechanical and chemical effects, what are the atomistic mechanisms governing the brittle to ductile transition in crystals, why the introduction of nano-sized twins can significantly increase the rate sensitivity of nano-crystals, and how domain structures affect the reliability of ferroelectric ceramics and thin films. To address these problems, which involve multiple length and time scales, he has used a variety of modeling techniques, such as molecular dynamics simulation, reaction pathway sampling, and the inter-atomic potential finite-element method. The goal of his research is to make materials modeling predictive enough to help design new materials with improved performance and reliability.

Xia began at Georgia Tech in Fall 2011. Prior to joining Georgia Tech, he was a postdoctoral researcher at the Graduate Aerospace Laboratories of the California Institute of Technology (CALCIT).

Streator’s research is concerned with the interactions between contacting surfaces, with particular emphasis on the roles played by surface roughness and by intervening liquid films. Much of this research is motivated by problems of adhesion or “stiction” that is prevalent in small-scale devices such as microelectromechanical systems (MEMS) and in the head-disk interface of computer disk drives. As device form factors continue to shrink the role of surface forces, such as liquid surface tension become increasingly dominant as compared to inertial forces. In this regard Streator has been interested in developing models that consider the interplay between liquid-drive capillary stresses and elastic restoring forces. This work has led to models of contact instabilities force generation predictions for both smooth and rough interfaces.
