About Lab Research

Dr. Ren-Hua Chung’s Lab focus on three research areas: statistical method development for genetic data, software development for genetic data analysis, and complex disease association analysis. We are developing novel statistical association tests, which aim to identify candidate genes associated with complex diseases based on human genetics data. We are particularly interested in developing family-based association tests. These tests include single-variant tests, gene-based tests, pathway analysis methods, and gene-gene interaction methods. With the high-throughput technique to generate genetic data, it has become important to develop efficient software to analyze the big data. We are developing efficient software packages that integrate difference resources such as public databases, bioinformatics tools, and statistical methods for genetic data analysis. Moreover, we are involved in several complex disease studies, such as metabolic syndrome, hypertension, and schizophrenia research.
