About Per-Erik Olsson

At Örebro University, Professor Per-Erik Olsson is working on the development of new sensitive biological methods for risk analysis. To improve the accuracy of risk analysis, work is underway to link computer-based machine learning methods to studies of toxicogenomic effects in the environment.

A research project led by Per-Erik Olsson "BioImpakt - an intelligent platform for automated risk analysis", which is supported by ORU Innovation, has been included in the Royal Academy of Engineering Sciences (IVA) top 100 list.

The research project was ranked among the top 50 and Per-Erik Olsson is therefore included in the group that will present its research project during this year's Research2Business (R2B) Summit, which will hopefully be held in September 2020 in Stockholm
