Research Opportunities

My research interests include structural dynamics, computational mechanics, structural response to wind and blast loading, and computational analysis of progressive collapse vulnerability. If you're interested in these topics, the following research opportunities are available at NIST; please contact me if you're interested:

Summer Undergraduate Research Fellowship program at NIST

The 2013 program ran from May 23 - August 9, 2013. Applications for the 2014 program will be due in early February 2014. Further information can be found at the following links:

NRC/NIST Postdoctoral Research Opportunity: Computational Modeling of Progressive Structural Failure and Collapse

Research focuses on modeling the dynamic collapse of multistory steel and reinforced concrete buildings under initiating events such as column failure as a result of blast loading. In progressive collapse scenarios, structural members typically undergo large displacements and rotations, and connections are subjected to large tensile forces not anticipated in traditional designs. Accurate characterizations of the failure modes and the resulting nonlinear load-deformation behavior of connections in such scenarios are critical for determining whether or not a collapse can be arrested. Opportunities exist for (1) the development of simple yet accurate modeling approaches that enable rapid collapse analysis of large structural systems, (2) comparison and quantification of the progressive collapse resistance of different types of structural systems, and (3) development of performance criteria and methods to mitigate progressive structural collapse for both new and existing structures. Emphasis is placed on model validation against both high-fidelity finite element simulations and experimental tests of structural subassemblies.

This Research Opportunity is available through the National Research Council Postdoctoral Research Associateship Programs only to US citizens who have held their doctorate for less than five years at the time of application. Further information can be found at the following links:
