I received a Ph.D. in Structural Engineering and Structural Mechanics from the University of Colorado-Boulder in 2017. I was then appointed a postdoctoral researcher assistant position where I worked on investigating crack propagation effect on the fracture resistance of composites material. My core mission in educating and advising is to engage students and prepare them for successful careers in civil and mechanical engineering by inspiring them to become the next generation of engineering innovators. My background in engineering gives me the critical knowledge and skills to modernize the curriculum and ways of teaching to better prepare students for this rapidly changing industry. My goal in all of the courses I teach is that each student develops a picture of the world at the microstructure level and couples that picture to the structural analysis by which we explain the mechanical behavior of the material.
Research interest and motivation:
Motivated by recent advances in material design methods that allow for the controlled engineering of microstructure, I studied the impact of microstructure on the mechanical behavior of composite material. I research ways to control the amount of crack development and to possibly improve the material’s reliability by controlling the spatial statistics of the particle microstructure in the matrix of a composite material. Recent developments in microscale fracture testing methods have revealed a greater sensitivity to the presence of particles as seen in random heterogeneous materials such as rock and ceramics.
My primary research interest combines experimental investigation with mechanics of materials theory and statistical analysis. In addition, I investigated the performance of construction materials in particular the reliability testing of bridge decks and I developed extensive knowledge of infrastructure resiliency. I found that the performance of the decks tended to converge to a certain state over time. Based on my findings, I proposed a global health index to identify the state-transition of in-situ deck conditions to reliably quantify performance and overall health.
