Background and activities
Research interests
My research interests are within the field of process systems engineering, with a strong focus on modelling, numerical optimization and control. By linking methods from optimization and control theory, my goal is to systematically develop practically applicable solutions for operating process systems in a safe, reliable, and economical way.
Topics in this area include
- Optimization-driven methods for optimal operation and control strategies
- Real-time optimization and predictive control
- Quantitative data methods for optimization and control of process systems
Current research projects
- Fast hierarchical economic optimization of dynamic systems, FRIPRP/IKTPLUSS Young Researcher Grant funded by the Norwegian Research Council
- Estimation of unmeasured process variables for subsea processing systems, Funded within the SUBPRO center for research-based innovation SUBPRO SFI
- Operational strategies for extending the remaining useful life of subsea processing systems, Funded within the SUBPRO center for research-based innovation SUBPRO SFI
