Welcome to my homepage!

I am a Danish engineer and hold a Ph.D. degree in nanophotonics. Today, I work as Head of Team of Sales and Marketing in the company TICRA in Copenhagen.
Previously, I worked for six years as Research Engineer in TICRA with a focus on R&D, analysis and design of antennas for space applications:

Large European Deployable Reflector: RF Modeling and Measurement Correlation, AP-S/URSI (2021) High-Frequency CubeSat Platform Scattering UsingHigher-Order Method of Moments, AP-S/URSI (2019) Multi-Feed-Per-Beam Antenna Concept for High-Performance Passive Microwave Radiometers, ESA Antenna Workshop (2018) Feed Array Breadboard for Future Passive Microwave Radiometer Antennas, EuCAP (2018)Large Deployable Antennas Benchmark for Contoured Beam Mission in C Band, EuCAP (2018)Advances on High-Performance Curved Reflectarrays for Telecommunication Applications, AP-S/URSI (2017)Advanced Techniques for Grating Lobe Reduction for Large Deployable Mesh Reflector Antennas, AP-S/URSI (2017)Full-Wave and Multi-GTD Analysis of the Ice Cloud Imager for MetOp-SG, EuCAP (2017)

Book: Surviving and Succeeding the PhD

I am editor and co-author of the book “The Nordic PhD: Surviving and Succeeding”, an edited book written for Ph.D. students and published in 2018.
The book is part of an international series and follows editions in Aotearoa New Zealand, Australia, the U.K., U.S., and South Africa.
In addition to being an editor, I authored chapter 5 “Writing the PhD Thesis: Planning, Getting Started and Getting Done” of the book.

Ph.D. project and research topics

I obtained my Ph.D. degree in 2015 from DTU Fotonik at the Technical University of Denmark (DTU).
During the Ph.D, I was a member of the Nanophotonics Theory and Signal Processing group.
Research topics included:

  • Photonic crystal cavity-waveguide structures
  • Quasi-normal modes of leaky and resonant nanophotonic systems
  • Computational techniques for nanophotonics
  • Optical properties of plasmonic nano-dimers
