Dr Adam Crewe is based in the Department of Civil Engineering where he examines the likely earthquake impacts that lead to the damage of buildings, bridges, dams, power stations and other built environments, using Bristol's innovative 鈥渟haking table鈥� simulation. Dr Crewe's projects include an analysis of ageing nuclear reactors to assess their ability to survive earthquakes and modelling the impact of earthquakes on Masonry walls that do not contain cement mix in the bonding mortar. Dr Crewe has been part of earthquake investigations in Japan and in Chile as a member of the formal Earthquake Engineering Field Investigation Team that reviews earthquakes globally. He is a member of the Society of Earthquake and Civil Engineering Dynamics (SECED), and Technical Advisor to an education outreach project called IDEERS (Introducing and Demonstrating Earthquake Engineering Research in Schools).

Zeghal's research interests include: Computational Soil Micro-Mechanics, Geotechnical-System Identification, Seismic Response Monitoring, and Information Technology Applications in Geomechnics. He is active with the Center for Network for Earthquake Engineering Simulation (CEES), Scientific Computation Research Center (SCOREC) and the Inverse Problems Center (IPRPI). 

The failure of geosystems due to natural or man-made hazards such as hurricanes, floods, earthquakes, or terrorist attacks may have monumental repercussions, sometimes with dramatic and unanticipated consequences on human life and the country鈥檚 economy. Zeghal鈥檚 research focuses on three areas that are central to the national effort to reduce the impact of these hazards: (1) multiscale modeling of geosystems, (2) model validation and calibration, and (3) development of improved optimal design tools. 

The methodology of evaluating and predicting the performance of geosystems is undergoing a significant paradigm shift. Computational simulations are destined to become more prominent than empirical approaches and will ultimately become the main tool for analysis and design of civil systems. A hierarchy of adaptive and cost-effective computational models capable of accurately predicting the multiscale and multiphysics response of geosystems is being developed. This hierarchy enables a seamless handling of the initiation and evolution of the various response and failure mechanisms of soils under extreme loading conditions. The hierarchical models range from homogenized continuum to discontinuous coarse-particle formulations. A class of innovative system identification and inverse problem tools are being developed to calibrate these models using experimental data ranging from soil sample and centrifuge tests to full-scale and field tests. This new generation of computational procedures is being translated to practice through careful interactions with practitioners (from industry and government laboratories) and the introduction of changes in the educational curricula of our students.

Dr. Prager is co-director of the . His research is focused on the policy and economics of disasters and has used computable general equilibrium analysis to estimate the macroeconomic impacts of environmental policy, natural disasters, and terrorism events. Prior to joining CSUDH, Prager was a postdoctoral research associate at USC Price School of Public Policy and Center for Risk and Economic Analysis of Terrorism Events (CREATE), working with numerous Department of Homeland Security agencies on different policy analyses.

Andy Bobyarchick teaches applied geophysics at UNC Charlotte. His long-term research interests include the tectonics and regional geology of the Southern Appalachian Mountains, particularly within the eastern crystalline core of the chain.
For several years, he has taught an intense, hands-on summer institute for in-service K-12 schoolteachers. This field- and lab-based course is oriented on content and experience. He is also actively involved in developing online physical geology courses for non-science majors or teachers through UNC Charlotte and through the UNC general administration.
Bobyarchick received a Ph.D. in Geological Sciences from SUNY Albany. A former research scientist at the U.S. Geological Survey, he is a member of the Geological Society of America, Carolina Geological Society, American Geophysical Union, Association of Environmental and Environmental Geologists and Sigma Xi.

Alessandro Palermo is an expert in the seismically safe design of buildings and bridges, with an additional focus on sustainability. He holds twos patents in mass timber construction, one of which is consider the basis for the advancement of seismically resilient technologies for timber construction and adopted in several buildings around the world.
Palermo has expertise in material degradation and potential mitigation strategies. For example, one of his recent projects aims to improve the lifespan of bridges by using innovative materials and by understanding the impact of corrosion on a bridge’s seismic performance. He also has done work on using waste materials, such as tires and glass, to improve the seismic performance of concrete structures.  
Palermo expertise branches out to digital construction as well. He is currently working on an extensive testing program to quantify the performance of 3D Printed concrete houses during earthquakes, the Achilles’ heel of the technology.
