I am a senior researcher in the Energy Modelling and Automation research group at NORCE Energy. I hold a PhD from University of Bergen. I am currently leading Drilling automation and autonomy, in the SFI DigiWells.

Before joining IRIS (now NORCE) in 2010, I worked as a research fellow in the Algorithms group at the Department of Informatics, University of Bergen, doing research in Theoretical Computer Science and Discrete Mathematics, most of it on Algorithmic Graph Theory which was also the topic of my PhD thesis.

At NORCE, I have been working in projects related to drilling automation both as a researcher and in project management. Lately, I have been working on autonomous drilling within the Demo 2000 project: Demonstration of Automated Drilling Process Control, supported by AkerBP, Equinor, Norwegian Research Council, Repsol, TotalEnergies, Vår Energy and Petrobras. I was Technical Leader for Autonomous Drilling - research, development, testing and demonstration in this project. Other projects where I was involved in include DrillTronics™, which is an advanced drilling assistance tool and is now commercialized by Sekal AS, projects on automated fluid processing, different case studies for industry, projects related to human factors in automated drilling and projects related to testing and verification of new technology within drilling automation and digitalization.

Key research topics I have been focused on during last years are real-time simulation of drilling process, development and implementation of model-based drilling automation applications, mathematical modelling, efficient knowledge representation, self-calibrating models, decision support systems, online learning, uncertainty estimation and methods for prediction of risk level in decision-making systems.

I hold a part-time position as Associate Professor at University of Bergen, Department of Informatics.
