研究方向:

 Mammalian genomes consist mostly of non-coding sequences. Within this massive proportion, previously misclassified as “junk DNA”, resides elements that function to regulate normal transcriptional programs. I am particularly interested in two classes of non-coding sequences: cis-regulatory elements (transcriptional promoters and enhancers) and endogenous retroviruses. The research of my laboratory focuses on dissecting how non-coding sequences are epigenetically regulated in both normal development and disease. We utilize various epigenomic and cell biology tools to delineate epigenetic pathways that modulate the activities of cis-regulatory elements and endogenous retroviruses, and their downstream effects on gene expression. Specially, I am interested in 1) elucidating the function of endogenous retroviruses in cellular differentiation during development; 2) determining the function of chromatin modifiers in progenitor and stem cells; and 3) uncovering the role of chromatin modifiers in melanomas.
