Big insight from big data

New! Highlights 2020

The project's contribution to the Centre for Digital Life Norway annual report 2020.

Co-reporting with the PerCathe project

Our work on drug synergy prediction has been particularly important in 2020. We developed Bayesian methods to estimate drug synergy in drug screening experiments, on the basis of heterogeneous types of data.

We are now able to estimate when two cancer drugs are more efficient in killing cancer cells than either drug on its own. We published three R-packages, because making software easily available to the public is essential for open science.

Our work is fully cross-disciplinary, merging the competence from statisticians, biologists, clinicians, bioinformaticians, molecular biologists, in our team.

Project overview

Project lead: Arnoldo Frigessi
Institution: University of Oslo and Oslo University Hospital

Research group

The aim of the project is to develop statistical and machine learning methods in the health sector, among others. The research includes modelling of early development of cancer, personalised cancer therapy, analysis of health data from hospitals, as well as epidemiological predictions to improve public health.

Innovation: The researchers in BigInsight develop analytical tools to extract knowledge from large databases. 12 partners contribute to the project, both private and public enterprises.

BigInsight is a Centre for Research-based Innovation, funded by the Norwegian Research Council.
