Research Interests: 

Dr. Ye Liang’s general research interests include:

  • Bayesian statistics, Bayesian hierarchical models, Bayesian computations
  • Spatial statistics, spatio-temporal models, dynamic state-space models
  • Gaussian graphical models, Markov random fields, lattice data
  • Survival analysis, reliability analysis, lifetime data 

Dr. Ye Liang’s research focus in the Oklahoma EPSCoR project is integrated statistical modeling and analysis for social-ecological data. Currently he is particularly involved in modeling ecological processes such as soil moisture, precipitation and streamflow.

Difficulties are twofold: First, most processes are nested with each other and exact physical relationships are unclear; Second, data used for analysis are from various observational sources and are highly variable. Dr. Ye Liang’s main objective in this project is to apply Bayesian methods, along with other cutting-edge statistical tools, to integrate these processes and data in a theoretically justified modeling framework.
