Lab & Research Interest

My primary research interest is in studying the causes and consequences of epigenetic variations in humans, and their interactions with transcriptomics to alter phenotypic changes, using computational methods on large-scale genomic datasets (e.g. gene expression, methylation, genotyping). My current research topics include:

(1) Identifying the epigenetic biomarkers of healthy ageing (e.g. age-related phenotypes, age-related diseases);

(2) Establishing a computational platform for other researchers, and improving the software for data interpretation;

(3) Understanding the interplay between gene-gene and gene-environment interactions
