John van de Lindt is a civil engineering professor in the College of Engineering at Colorado State University. Since joining CSU in 2004, he has led numerous projects funded by the National Science Foundation. In 2005, he received a four-year, $1.24 million grant from NSF to develop a new design approach for taller woodframe buildings in earthquake-prone areas in collaboration with several other major universities, which led to the capstone test in Japan.
After Hurricane Katrina hit in 2005, he led a team of scientists from around the country to examine how building codes in Louisiana and Mississippi contributed to the massive destruction left by the hurricane. See the press release here.
In 2007, van de Lindt also collaborated with Oregon State University to study the effects of the force of hurricane-strength waves and their damage to woodframe residential buildings.
Van de Lindt has also worked under an NSF grant with Bogusz Bienkiewicz, a wind engineering professor in CSU's civil engineering department, to connect a state-of-the-art wind tunnel with a large structural load frame to simulate the effect of wind on structures. They built a connection in "real time" over the Internet 2 backbone--a faster Internet used primarily for research purposes.
Before joining Colorado State, van de Lindt worked as an assistant professor at Michigan Technological University. He obtained his master's and doctoral degrees from Texas A&M University.

Rachel Davidson is an Associate Professor in the Department of Civil and Environmental Engineering at the University of Delaware, and a core faculty member at the Disaster Research Center. After completing her Ph.D. from Stanford University, she spent two years at the University of North Carolina at Charlotte, then six years at Cornell University, both as an Assistant Professor of Civil Engineering. Following a year as a Visiting Assistant Professor at Columbia University, she joined the faculty at the University of Delaware in 2007. Davidson conducts research on natural disaster risk modeling and civil infrastructure systems. A co-PI of NEESWood, she is leading the effort to assess the societal risk implications of the new performance-based seismic design philosophy for woodframe buildings. Specifically, she and her graduate research assistant, Greg Black, are developing and analyzing empirical relationships between loss, seismic ground motion intensity, and performance expectations to inform the specification of seismic performance objectives for woodframe buildings and to understand the implications of those performance objectives for societal risk.
