Welcome
My research has pursued to model and simulate stochastic processes in the real world, such as disease spread based on human mobility, interdisciplinary citation flow across subfields of sciences, and information diffusion across heterogeneous social networks in online social media or mobile telecommunications. Interestingly, I find that such disparate real-world domains exhibit common nonlinear dynamics, and I am super excited in uncovering underlying mechanisms beyond disciplines.
My PhD study had more focused on understanding topic-sensitive information diffusion patterns across different types of social media in both model-driven and model-free ways. I obtained my PhD in Computer Science at The Australian National University and Master's degree in Computer Science at University of Southern California.
