Welcome to my homepage!

I am a Danish engineer and hold a Ph.D. degree in nanophotonics. Currently, I work as research engineer in the company TICRA in Copenhagen, where I focus on R&D, analysis, and design of antennas for space applications. Recent topics and projects include:

  • Large mesh reflector and reflectarray antennas
  • Radiometers and focal plane arrays for Earth observation
  • RF modeling of space mission instruments

Large Deployable Antennas Benchmark for Contoured Beam Mission in C Band, EuCAP (2018) Advanced Techniques for Grating Lobe Reduction for Large Deployable Mesh Reflector Antennas, AP-S/URSI (2017) Feed Array Breadboard for Future Passive Microwave Radiometer Antennas, EuCAP (2018) Full-Wave and Multi-GTD Analysis of the Ice Cloud Imager for MetOp-SG, EuCAP (2017)

New book in 2018

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
