I am an Assistant Professor of Computer Science & Engineering at Mississippi State University, focusing on dynamics over graphs (see details of my research interests). I obtained my Ph.D. at Virginia Tech in 2020, under the supervision of Dr. Chang-Tien Lu. For students interested in me, check ways to work with me. If interested in my courses, please check the course syllabi.

Research Interest: My research focuses on graph dynamics, leveraging methodologies such as spectral graph theory, uncertainty quantification, higher-order analysis, and physics-inspired approaches. Currently, I am particularly interested in the dynamics of coupled and interdependent networks. My collaborations span diverse applications, including Social network 1, Transportation 2, Spatial epidemiology, ecological network 3, Brain network 4, Genetics 5, Circuit 6. Also, I have been working on spectral method 7, Uncertainty Quantification 8, LLM/transformers, AI education 9
