Combinatorial inference
Combinatorial inference develops novel theories on high dimensional universality phenomenon and combinatorial information-theoretical lower bounds and proposes methods to conduct the global inferential analysis on the topological properties of the graphs in the graphical models and other combinatorial structures.

Complex Biomedical Data Analysis
Modern statistical methods deal with biomedical datasets with complex structures including high-dimensionality, heterogeneity, heavy-tailness, time-dependency and so on. Complex data inference aims to develop a new generation of inferential methods like hypothesis testing, confidence intervals and false discovery control for complex datasets.
