Dr. Yong-Jie Hu is an assistant professor of Materials Science and Engineering who joined the department in January 2021. He received his BE degree from Tsinghua University and MS degree from Tohoku University. In 2016, he obtained his PhD degree in Materials Science and Engineering from the Pennsylvania State University. Before joining Drexel, he was a postdoctoral research fellow at the Pennsylvania State University and subsequently at the University of Michigan. The research of Hu’s group (Materials Computation and Informatics Group) focuses on investigations of mechanical, thermodynamic, and electronic properties of materials by applying and integrating a variety of cutting-edge computational techniques, including first-principles calculations, molecular dynamic simulations, the CALPHAD approach, multiscale modeling, and machine learning approaches. By closely collaborating with experimentalists, his group aims to develop quantitative mechanisms, models, and databases to guide and accelerate the design and manufacture of advanced materials.
