Dr. Maragh specializes in the chemical and mechanical characterization of highly heterogeneous composite materials using spectroscopic chemical characterization techniques, local and macroscale mechanical testing, unsupervised machine learning, and finite element modeling.

Dr. Maragh has experience chemically characterizing materials using scanning electron microscopy (SEM), quantitative energy dispersive X-ray spectroscopy (EDS), and confocal Raman microscopy (CRM). She also has experience mechanically characterizing composites using microindentation, nanoindentation, and compression testing. Dr. Maragh uses unsupervised learning techniques in the analysis of large sets of spatially resolved chemical data to better understand the phases present in complex composites of poorly understood composition, and she has experience in interfacing this information with finite element modeling (FEM) to observe and quantify their effective behavior and properties.

As a PhD researcher at the Massachusetts Institute of Technology, Dr. Maragh focused on the characterization and modeling of a range of highly heterogeneous composites, including ancient Roman concrete, ordinary Portland cement-based materials, parchments, pigments, and kidney stones. During her PhD, she also studied the stability of unreinforced masonry structures using both numerical methods and scale model experiments. As a Masters student in the MIT Marine Robotics Group, she worked on the cooperative localization and navigation of unmanned surface and underwater vehicles.
