The overarching goals of our research are to decipher the noncoding human genome, understand different modes of gene regulation and elucidate mechanisms by which noncoding genetic variants affect human traits and disease risk.

Transcriptional regulation

Large-scale projects including ENCODE and Roadmap Epigenomics have already documented ~1M putative enhancer elements in the human genome. These regions were demonstrated to be strongly enriched for disease risk SNPs detected by GWAS studies. Key current challenges that research in our lab tries to advance are:

(1) Improve global mapping between enhancers and their target genes;

(2) Pinpoint causal genetic variants which modulate binding affinity of transcription factors thereby affecting enhancer activity; and

(3) Characterize target genes and biological processes that are affected by risk SNPs, thereby elucidating molecular pathways that are relevant for the etiology of complex diseases.

(4) Delineate interplays between the genome 3D organization and transcriptional regulation.   


We recently developed a novel method for detecting transcriptional programs that link cell differentiation and disease risk, by integrative analysis of single-cell RNA-seq and GWAS data. [PubMed]

Regulation of transcript stability and translation efficiency.


Gene regulation is a multi-layered process. While the main layer is transcriptional regulation, other layers remain under-explored. We aim at elucidating post-transcriptional mechanisms that control gene expression by modulating mRNA stability and translation efficiency. These layers are mainly regulated by cis-elements embedded in transcripts’ untranslated regions (UTRs). We study how genetic variation in UTRs affect gene expression and human traits.

We introduced the concept of poly-adenylation QTLs (pA-QTLs) and discovered hundreds of SNPs that affect gene expression by interfering with the canonical signal that control mRNA polyadenylation (the PAS signal in 3’UTRs). [PubMed]

Functional interpretation of omics data

With the ever-increasing volume of publicly available genomic, transcriptomic, and proteomic data, it remains a great challenge to uncover biological and biomedical insights out of it. We analyze different systems-biology approaches for enhancing the functional interpretation of such data, including 

(1) network-based and (2) gene-set analyses.


Both approaches build on the amplification of weak signals, achieved by consideration of the coordinated response of many genes that function in the same biological process, where individually most of them show only mild signal that does not reach statistical significance in individual gene-level tests.
