The tectonic evolution of Antarctica
… tectonics. Although the justification for long distance correlation of individual tectonic regions is called into question, four stages are illustrated in the evolution of the present Southern Hemisphere.

Statistical inference for high-dimensional data
… proposed methods. In the first chapter, we study distance covariance, Hilbert-Schmidt covariance (aka Hilbert-Schmidt independence criterion [Gretton et al. (2008)] and related independence tests under the high dimensional scenario. We show that the sample distance/Hilbert-Schmidt covariance …

Dependence testing in high dimension
… The test is constructed based on the pairwise distance covariance and it accounts for the non-linear and non-monotone dependencies among the data. Our test can be conveniently implemented in practice as the limiting null distribution of the test statistic is shown to be standard normal. It …

Statistical Modeling for High-dimensional Compositional data with Applications to the Human Microbiome
… hypothesis, together with a nonparametric and distance-based testing method. Furthermore, we utilize multiple variable-selecting models, including LASSO, elastic net, ridge regression and cumulative logit model, to identify the most important subset of variables. This dissertation is structured …

Exploring topological data analysis in gene expression data topology-driven biomarker discovery and clinical outcome prediction in oncology
… multiple co-expression measures—namely, Pearson Correlation, Distance Correlation, and Weighted Topological Overlap (wTO) computed with both Pearson and Distance-based adjacencies. These topological features were analyzed using Random Forests. In parallel, we compared the predictive performance …
