Dr. Ranran Wang’s major research interests are statistical models and computational tools to analyze relational data, including longitudinal data, social network data, and spatial processes. In previous research work, she quantitatively analyzed data to answer scientific questions in meteorology, sociology, and ecology. She is also interested in optimization methods for statistical simulation and computational Bayesian analysis. She is proficient with mathematical and statistical software including Matlab, R, and SAS. During her Ph.D program, she provided statistical consulting to faculty and students at the University of Washington.

Post-processing and Verification Study in Weather Forecasting: Developed linear regression models and classification methods, as well as their nonlinear analogs (e.g. neural networks) in order to improve ensemble forecasts from numerical weather prediction models. Analyzed temporal and spatial correlations of observations and their impacts on rank histogram verification tools.
Bayesian Analysis of Social Network Models and Applications: Carried out Bayesian inference on exponential-family random graph models (ERGMs) to improve the effectiveness and computational effciency of ERGM and resolve degeneracy issues. Tested and implemented novel Markov-chain Monte-Carlo simulation algorithms. Applied ERGMs to investigate the graphical structure and underlying generation mechanism of social networks.
