As a graduate student in the lab of materials science and engineering professor Alex Jen, Jiaxu worked on designing multi-functional binders for lithium-sulfur batteries based on molecular interactions. Different strategies are proposed to solve the cracks issue and lithium polysulfide dissolution issue in sulfur cathode to achieve high-loading, long-cycle-life sulfur cathode. Jiaxu was a 2017 Clean Energy Institute DIRECT data science trainee. In addition, Jiaxu completed the MolE Data Science Option. Since completing his Ph.D. in 2022, Jiaxu began working in the private sector as a software engineer to design data platforms.
