Experience
2026 - nowMember of DeiC e-ressource committe (Danish e-infrastructure Consortium)
2022 - nowAssociate Professor, AAU Energy, Aalborg University
2022 - nowMember of steering committee, DaCES (Danish Centre for Energy Storage)
2020 - 2024Research Group Leader of Multiphase Flows and Heat transfer, AAU Energy, Aalborg University
2019 - nowBoard member, DANSIS (The Danish Society for Industrial Fluid Dynamics)
2018 - 2022Assistant Professor, AAU Energy, Aalborg University
2014 - 2017PhD Student, AAU Energy, Aalborg University
- Focus was on fluid dynamics using computational methods. The adhesive behaviour of small micron-sized particles in turbulent flows was investigated by coupling the Discrete Element Method (DEM) to Large Eddy Simulations (LES) using the open-source software LIGGGHTS, CFDEM and OpenFOAM.
