• Computational Toolbox for Discovery of Prognostic Biomarkers for Survival Analysis
The Client : Javna agencija za raziskovalno dejavnost RS
Project type: Research projects ARRS
Project duration: 2021 - 2024
  • Description

In the project, we will design and develop an interactive, visualization-based exploratory analysis toolbox to assist in finding molecular prognostic biomarkers from high-throughput molecular data and survival data obtained in clinical trials. The project will devise computational and machine learning methods to search for biomarkers, encapsulate them within interactive components with a graphical user interface, and provide visual programming to stitch these components into data analysis pipelines. The constructed methods and toolbox will support collaborations between the data scientists and domain experts-physicians, biomedical or pharma researchers-to sift through the molecular cell-response data of thousands of genes to find those that correlate most with survival. The proposed tool will access existing models, ontologies, and knowledge bases to speed up the interpretation and provide semi-automatic explanations of results. This is an applied project where we are teaming up with Genialis, a data science company specializing in computational support for precision medicine.
