Jun 2012 - Dec 2015

Graduate Research Assistant

Auburn University

Auburn, Alabama Area

My research focused on improving nanoindentation of thin films on substrates. In cases such as thin films, phenomena such as sink-in or pile-up may affect extraction of material properties. I worked to solve these problems and understand the material characteristics that drive them. Plastic material properties were probed, as well, which has been lesser studied with nanoindentation.Initially, I examined the abalone shell structure, or mother-of-pearl, as an architecture for protective armor applications. The mollusks were cultured in the lab and the shell structure was studied with changes in temperature. The end goal was to engineer the growth of the abalone shell for a stronger material structure.
