My research group works on advanced statistical methods for large-scale inference, with applications in big genomic data to identify disease susceptibility genes and predict treatment response.

Analyzing large genomics data for disease phenotypes introduces challenging statistical problems. Despite the fact that genome-wide genetic variants data are regularly available in disease studies, confirmed disease susceptibility genes, or confirmed genotype-phenotype relationships, are limited. Critical barriers in statistical analysis include efficient computation for the large-scale (high dimensional) data, complicated dependency structures, weak and sparse signals, and confounded genetic effects with environmental factors. We consider testing procedures for screening large genome-wide data and develop powerful tests that are specifically developed to overcome the aforementioned challenges.
