“Our research investigates how regulatory information is encoded in DNA, how it is interpreted and how it is communicated across cells in multicellular organisms”
The development of complex organisms critically depends upon regulation of gene activity across dozens, hundreds or millions of cells in time and space. This regulation ensures the fidelity of development of complex structures and the overall function of the organism. Its disruption therefore often leads to disease.
We study gene regulation at the genome-wide level using computational genomics and epigenomics, as well as experimental transcriptomics and promoter activity mapping. Our major research interests focus on:
- Structure and function of gene promoters
- Function and genomic distribution of gene regulatory elements
- Function of transcription factors
- Regulation of the production of transcription factors i.e. transcriptional regulatory networks (TRNs)
- Association of different modes of regulation with epigenetic marks and their inheritance
- Transcriptional and translational regulation and dynamics in embryonic development
- The role of core promoters and their diverse architectures in vertebrate development and differentiation
- Emergence and evolutionary dynamics of conserved non-coding elements
Our recent work centres on the functional classification of core promoters, the development of methods to correctly assign regulatory elements to the genes they regulate, and the role of the epigenome in guiding development. Most of our work until now has been purely computational, either analysing publicly available data or in collaboration with experimental laboratories using high-throughput sequencing techniques such as CAGE, ATAC-seq, MNase-seq, RNA-seq, ChIP-seq and Hi-C. Since 2016 we also have experimental activity focusing on studying functional diversity of promoters in development and differentiation.
The boundaries of GRBs are highly consistent regardless of the thresholds or species involved (doi:10.1038/s41467-017-00524-5).
