Research and Teaching Interests

My interests are in characterizing the condition of structural systems using structural health monitoring technology and computational modeling tools. The goal of structural health monitoring is to measure the response of some critical infrastructure and to diagnose if, when, where, and how much damage has formed. This field relies extensively on topics in structural analysis and structural dynamics, which form the core of my teaching portfolio. Knowledge of the structure’s condition can then be forwarded to owners and engineers to make informed decisions regarding structural rehabilitation. My specific focus is on substructural monitoring, a set of divide-and-conquer strategies to better understand the safety of individual critical structural components. My research interests also branch out to studying the dynamics of how buildings collapse through laboratory testing and computational modeling, and predicting the time-dependent behavior of cementitious materials at the microscale level.
