Genomics: Future of Medicine
Genetic factors account for more than half of the phenotypic variations on the development of most common human diseases, such as mental disorders, diabetes, hypertension, and cancers. The previously identified genes only explain a small percentage of known inherited risk to develop each of these diseases. Most of the genetic factors are still unknown. The molecular basis of the missing heritability may lie in rare single nucleotide polymorphisms (SNPs), copy number variations (CNVs), gene-gene and gene-environment interactions, epigenetic changes, and other genomic mechanisms on the human genome.

Research in our laboratory aims to understand the genetic basis of these genomic variations and their roles in the etiologies of complex human diseases, particularly mental disorders and brain diseases (e.g., substance use disorders), using the latest high-throughput genomic platforms (e.g., microarrays and next-generation sequencing) and advanced computational tools, followed by functional validations of identified variants. Our studies will provide better understanding of the disease mechanisms towards novel development of early diagnosis, disease prediction, and personalized treatment.

Typical Research Design
The figure below shows the overall design of one of our recent studies. In this example, we have recruited unique, large patient cohorts, and recently completed genome-wide genotyping experiments. The next step is to leverage the big data to identify disease-associated genes using advanced computational tools.

Current Research Topics
1. Genome-wide association study (GWAS)
2. Copy Number Variation (CNV)
3. Meta-analysis
4. Gene discovery and fine-mapping
5. Next generation deep sequencing
6. Mental disorders and brain diseases
