Dr. Hojati worked on a variety of research studies that equipped her with the skills to conduct diverse research in material and structural program in the civil engineering discipline. These studies varied from the design and development of innovative and green construction materials, 3D-printing of concrete (additive manufacturing of concrete components), development of sustainable and resilient infrastructure, numerical modeling of structures, programming, and experimental work. Her current research is mainly focused on digital construction and how to alter the construction industry by utilizing additive manufacturing, commonly known as 3D-printing in sustainable projects. During her post doc at Penn State University, Dr. Hojati participated in the NASA 3D-Printed Habitat Challenge, where she successfully designed a composite material consisting of components indigenous to Mars and Earth. Her team at Penn State also designed a deployable printer system to utilize this material. They won four awards in different phases of this competition, and they printed the first-ever fully-enclosed 3D-printed structure on an architectural scale and in an almost autonomous process without any support structure.
