Josh has a degree in mechanical engineering with a focus on materials science. His senior research, published in the Proceedings of the National Academy of Sciences, was about magnetically driven three-dimensional manipulation and inductive heating of magnetic-dispersion containing metal alloys. Prior to attending law school, Josh worked at Yale University's technology transfer office (the Office of Cooperative Research), where he assisted with patenting and licensing inventions arising from Yale's labs.
In law school, Josh received the Lefever Prize for the best paper in the field of law and economics. As an undergraduate, he was awarded the Lichty & Waters Prize for high scholarship and original research in mechanical engineering.
