Haowei is a PhD student in nuclear science engineering whose research focuses on light-matter interaction and topological materials. Specifically, he uses coherent light (lasers) to manipulate the properties of materials and using materials to generate, detect, and manipulate light. He has also demonstrated that topological materials can have outstanding optical properties. He uses MATLAB for numerical modeling, including integration, optimization, and partial differential equations, to test ideas and/or obtain results easily, with far fewer lines of code, significantly accelerating his research. He also uses MATLAB to write code requiring large scale matrices, as well as visualization. Haowei earned a BS in physics from Peking University, China.
