Overview
Professor Gall’s research aims to develop a fundamental understanding of the relationship between the processing, structure, and mechanical properties of materials. His scientific contributions range from the creation and understanding of shape memory metals and polymers to the discovery of a new phase transformation in metal nanowires. His current research interests are 3D printed metals and polymers, soft synthetic biomaterials, and biopolymers with structured surface porous networks.
In addition to his research he has consulted for industry, the US Military and the US Intelligence Community, and served as an expert witness in multiple patent and product litigations. Finally, he is a passionate entrepreneur who uses fundamental scientific knowledge to hasten the commercialization of new materials and improve the effectiveness of existing materials. He founded two medical device start-up companies, MedShape and Vertera who have commercialized university based technologies in the orthopedic medical device space.
