During my research career I have observed “new” material systems develop and offer promise of wondrous device performance improvements over the current state of the art. Many of these promises have been kept, resulting in numerous new devices that could never have been dreamed of just a few short years ago. Other promises have not been fulfilled, due, in part, to a lack of understanding of the key limitations of these new material systems. Regardless of the material in question, one fact remains true: Without a detailed understanding of the electrical and optical interaction of electronic and photonic “particles” with the material and defect environment around them, novel device development is clearly impeded. It is not just a silicon world! Modern electronic/optoelectronic device designs (even silicon based devices) utilize many diverse materials, including mature dielectrics such as silicon dioxide/nitrides/oxynitrides, immature ferroelectric oxides, silicides, metal alloys, and new semiconductor compounds. Key to the continued progress of electronic devices is the continued development of a detailed understanding of the interaction of these materials and the defects and limitations inherent to each material system. It is my commitment to insure that new devices are continuously produced based on complex mixed family material systems.

Yang Wang joined Georgia Tech faculty in 2007. With a B.E. and an M.S. degree in civil engineering awarded by Tsinghua University in Beijing, China, he received a Ph.D. in civil engineering at Stanford University in 2007, as well as an M.S. in electrical engineering. Wang’s research interests include structural health monitoring and damage detection, decentralized structural control, wireless and mobile sensors, and structural dynamics. He received an NSF Early Faculty Career Development (CAREER) Award in 2012 and a Young Investigator Award from the Air Force Office of Scientific Research (AFOSR) in 2013. Wang is the author and coauthor of over 100 journal and conference papers, and currently serves as an associate editor for the ASCE (American Society of Civil Engineers) Journal of Bridge Engineering.

Lauren Stewart joined the Georgia Institute of Technology, Civil & Environmental Engineering faculty as an assistant professor in August 2013. She was promoted to Associate Professor, with tenure in 2019. She received her B.S. in Structural Engineering from the University of California, San Diego in 2004 and her Ph.D. in Structural Engineering also from the University of California, San Diego in 2010. She is a National Defense Science and Engineering Graduate Fellow, an US Air Force Summer Faculty Fellow, and a 2017 Rising Star in Structural Engineering. Prior to coming to Georgia Tech, Stewart was a Post Doctoral Scholar at the University of California, San Diego from 2010 to 2013. From 2006 to 2013, she worked a Senior Blast Engineer at Karagozian & Case Structural Engineers in California where she holds a PE license.

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.

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).

Neu's research involves the understanding and prediction of the fatigue behavior of materials and closely related topics, typically when the material must resist degradation and failure in harsh environments. Specifically, he has published in areas involving thermomechanical fatigue, fretting fatigue, creep and environmental effects, viscoplastic deformation and damage development, and related constitutive and finite-element modeling with a particular emphasis on the role of the materials microstructure on the physical deformation and degradation processes. He has investigated a broad range of structural materials including steels, titanium alloys, nickel-base superalloys, metal matrix composites, molybdenum alloys, high entropy alloys, medical device materials, and solder alloys used in electronic packaging. His research has widespread applications in aerospace, surface transportation, power generation, machinery components, medical devices, and electronic packaging. His work involves the prediction of the long-term reliability of components operating in extreme environments such as the hot section of a gas turbine system for propulsion or energy generation. His research is funded by some of these industries as well as government funding agencies.
