Research Objectives

Transcript variant expression is the combination of transcriptional and post-transcriptional regulation. The regulatory environment at promotor regions is studied by short reads, but these do not reveal the contiguous promoter methylation landscape, which could be captured by LRS. Moreover, methods for integration of multi-omics long reads data do not exist. Our objectives are: 

  • Develop a wet-lab protocol for long reads ATAC-seq and Nascent-seq using Nanopore. Apply to H1 human cell line.
  • Develop an analysis pipeline to process lrATAC-seq data to identify chromatin accessibility and methylation.
  • Integrate H1 lr-ATAC-seq and Nascent-seq data with LRGASP lrRNA-seq to infer transcript-specific regulatory patterns.
  • Implement methods in the SQANTI and tappAS software tools.

Envisioned Secondments

  • ITT (Nicassio/Leornardi): Develop lrATAC-seq assay.
  • Nanopore (Aino Javelin): Develop lrATAC-seq assay.
  • UCSC (Angela Brooks): Learn FLAIR to pre-process Nanopore data.

We are interested in understanding functional aspects of gene expression by combining a wide variety of high-throughput molecular techniques, including transcriptomics, epigenomics, proteomics, metabolomics, metagenomics and single-cell data, both for model and non-model species. Our lab develops statistical methods and user-friendly software tools to analyze these multi-omics data. Our most current interest is the application of long reads sequencing technologies for transcriptome analysis, the integration of multi-omics data to understand isoform regulatory biology, and the combination of environmental sequencing data to investigate the function of Microbial Dark Matter.
