His research centers on terahertz time-domain spectroscopy (THz-TDS), ultrafast photonics, and the optical properties of two-dimensional materials such as graphene and MoS2. He investigates complex conductivity, plasmonic effects, and dielectric permittivity using advanced terahertz nanoscopy and solid-state detection methods. His work bridges fundamental physics with practical applications in sensing, materials characterization, and next-generation optoelectronic devices.

The recent publications reveal a strong trend in applying machine learning to THz spectroscopy, probing anisotropic responses in nanostructures, and extracting material properties at the nanoscale. Key fields include terahertz photonics, 2D materials, metamaterials, and nonlinear optics, with interdisciplinary applications in energy, quantum technologies, and biomedical sensing.

Dr. Jepsen has supervised multiple PhD students in active projects such as Terahertz Lightwave Electronics and Confined Water in Artificial and Biological Systems. He has secured significant research grants, including projects on perovskite solar cells and non-invasive skin analyte monitoring. His collaborations span institutions in Denmark and internationally.

He is involved in the Ultrafast Infrared and Terahertz Science research group at DTU, where he leads experimental efforts in terahertz generation, detection, and spectroscopic applications. The team focuses on developing novel instrumentation and methodologies for ultrafast optical science.
