About
Research focus on methods and models for resource planning og control. Since 2015, I have been working together with the healthcare sector on projects related to resource planning of imaging equipment (MRI and CT), surgery scheduling, personnel scheduling, and planning of activities in outpatient clinics.
My doctoral thesis considered optimization of ICT services and data centers in the cloud computing area with a special focus on quality of service and power usage.
