Biography
Dr. XIA obtained his PhD degree from the Chinese Academy of Sciences in Jan 2013. He was a visiting scholar at the Department of Mathematics, Michigan State University from Dec 2009- Dec 2012. From Jan 2013 to May 2016, he worked as a visiting assistant professor at Michigan State University. He joined Nanyang Technological University in Jun 2016.
Research Interests
The last century has witnessed the tremendous advancement of Biological Sciences. The availability of massive biological data, high-performance computers, efficient computational algorithms, and mathematical and physical models have paved the way for Biological Sciences to undertake a historic transition from being qualitative, phenomenological, and descriptive to being quantitative, analytical, and predictive. Under this transition, modern Mathematical Biology will be fundamentally changed from macroscale modelings (of species, population, disease, blood fluid, etc) to molecular based analysis (of protein, DNA, gene, virus, etc).

Dr. XIA's group focuses on Molecular Based Mathematical Biology (MBMB). The essential idea is to use computational tools from PDE, differential geometry, algebraic topology and statistical learning to study the biomolecular structure, flexibility, dynamics, and functions. His recent interests are topological data analysis (TDA), topology based machine learning/deep learning models, and their applications in drug design.
