  • Sustainable photonics
  • Optical 3D measurement across scales - from macro to nano
  • Structured, multispectral illumination
  • Super-resolution microscopy (nanoscopy) for subcellular structure imaging
  • Endoscopy-based 3D imaging for interior spaces that are difficult to access
  • Event camera-based imaging for highly dynamic, low-latency scenarios
  • 3D-oriented programming and digital system integration of optical sensors
  • Translational application of optical measurement technology in industrial and clinical contexts

Current Mentoring​ and Teaching

Andreas is leading our stereophotogrammetry team and is currently (co-) supervising the student projects of:

  • Matthew     (PhD Thesis, previously Research Lab & Master Thesis, Medical Photonics)
  • Ade              (Research Lab & Master Thesis, Medical Photonics)

Andreas is lecturing in our Physical Optics & Optical Engineering lectures (Master Medical Photonics, Master Photonics, Master Physics), as well as regularly tutoring several undergraduate practical courses (for physics, photonics, medicine, biology, chemistry students).

Short Vita

Andreas came to Jena in 2009 to study physics at the FSU and graduated in 2015. During his studies, he produced a Bachelor Thesis on the combination of holography and interferometry and a Master Thesis on the application of the Moire effect to digital holography, under the supervision of Dr. Armin Kießling, both at the Institute of Applied Optics (Prof. R. Kowarschik, IAO).

He then specialized in precise optical 3D measurement techniques, e.g. stereophotogrammetry, and investigated approaches to optimize speckle-based methods, both on a hardware and post-processing side.

Andreas joined the Franke Lab @IAOB after his very productive PhD with Prof. Kowarschik. His scientific output includes multiple first-author papers and several technology patents, for which he has been awarded the 2022 Ph.D. Award of Dr.-Ing. Siegfried Werth Foundation. Andreas leads our charge into the macro-nano-verse, while broadening his expertise in industrial 3D measurements towards biological and clinical applications. At the same time, he is working towards a new research focus at IAOB, that he termed sustainable photonics. 

He was recently awarded within the FSUs IMPULSEproject to further push his research in multiscale structured illumniation.

Since May 2024, he is also the project leader and scientific coordinator of our BMBF funded consortium 3DVens.

Andreas has won several Science Slam competitions aimed at the broader public, including at the Day of Physics at FSU Jena and the Long Night of Science in Jena.

Besides being a scientist and mentor at FSU Jena, he is an avid basketball player and proud father of a young son.
