Bioinformatics

Today’s personalized medicine is based on in-depth knowledge of the genetic and epigenetic repertoire of diseases and the availability of novel agents for targeting altered genes and pathways. Therefore, automated and reliable methods for analysing and interpreting this data are needed to achieve maximum explanatory power, cost and time efficiencies in medical diagnostics.

We drive the in-silico arm of the entire molecular biomarker development process from omics discovery studies, candidate signature identification, platform and matrix transfer, technical verification studies to clinical validation studies. To resolve complex disease phenotypes, we also integrate multiple omics layers from multiple tissue types and/or body fluids with imaging, clinical or exposome data.

 

Our expertises include:

  • Study design: identification of use cases and target population, selection of target matrices and measurement platforms, cohort selection, good practices
  • OMICS technologies: data processing and analysis pipelines available for whole genome (bisulfite) sequencing, RNAseq, microbiome sequencing, DNA and Protein chip data, high throughput qPCR, single-cell sequencing (coming soon). Pipeline development including GUI.
  • Identification of candidate biomarker signatures: multivariate statistics, machine learning / AI, regulatory network analysis, gene set enrichment analysis, multi-omics integration, endotype discovery.
  • Technology and matrix transfer: our assay design pipelines support technology transfer from screening technologies (e.g. NGS) to easy-to-use, low-tech (PCR, ELISA) assays and matrix transfer from tissue to non-invasive body fluids.
  • Microbiome studies: analysis setup, data analysis and interpretation of results
  • Genome assembly: generation of contigs and scaffolds, gene identification and analysis, homology analysis
  • Development and validation of diagnostic signatures: validation of machine learning models based on data from clinical studies
