Artificial Intelligence (AI) at GIS

Advancements in AI technology and their application to comprehensive datasets for data prediction, classification, simulation, or modeling, represent the next frontier of genomics. With the nature of biological data which can be large, complex, heterogenous, and ever-changing due to evolution, AI bioinformatics tools have the potential to enhance analysis speed and generate valuable insights for the development of research.

At GIS, we complement our computational research in genomics with AI. This research includes, but is not limited to:

  • Analysis of DNA/RNA sequencing data and biomolecular structures for applications on read type detection, de novo assembly, DNA/RNA modifications, RNA folding, etc
  • Application on cancer research to improve treatments, discovery of new drugs and biomarkers
  • Metagenomic identification and analysis of novel species, virulence resistance determinants
  • Cancer drug response prediction, microbial surveillance in healthcare environments
  • Microbial surveillance in healthcare environments and antimicrobial resistance prediction
  • Analysis of transcriptional regulation using epigenomics data and identification of prognostic makers and drug targets
  • Development of machine-learning open-source software that improves the analysis of third generation RNA-sequencing data
  • Generative modeling of underlying biological processes
  • Image-integrated analysis of spatial transcriptomics data
  • Graph-based methods for learning and inference on spatial-omics data (eg, spatial cell clustering)
  • Mathematical optimisation and feature selection for transcriptomics (eg, DUBStepR)
  • Uncertainty quantification and predictive modeling of genetic networks
