The Department of Photonics Engineering at the Technical University of Denmark (DTU) is seeking a highly motivated postdoctoral candidate for a postdoc position within the field of mid-IR upconversion imaging and spectroscopy. The aim of this ambitious project is to open a new field: “mid-infrared transmission spectroscopy of wet biological samples”. The successful candidate will challenge the prevailing idea, that MIR transmission spectroscopy is not technically feasible for fresh bio samples (in vitro). In order to challenge this paradigm, the candidate need to overcome the exorbitant strong mid-IR absorption from water in the sample, while keeping sample illumination at a safe to avoid sample damage.

The candidate will set up a novel MIR spectrometer in the 6-15 µm range with ultimate sensitivity approaching the single photon limit. The ispectrometer is specifically designed for mid-IR hyperspectral bio imaging. A hyperspectral bio image shows both chemical content and morphology analogous to human colour vision when analyzing a “spot” on the skin of an apple. This technique has already showed remarkable results and will possibly/eventually(!) replace a more than 100 years old, gold standard technique for biopsy screening, based on staining (e.g. H&E staining).

The Optical Sensor Technology has researched for more than 10 years into hyperspectral upconversion imaging and has an on-going activity on hyperspectral imaging of bio-samples. Therefor the candidate will have access to both supervision/sparring as well as fully equipped laboratory facilities.

Responsibilities and tasks
The potential candidates are expected to work in a team and tackle interdisciplinary challenges that will involve:

  • Design and implementation of a unique and highly sensitive upconversion spectrometer, designed for the molecular fingerprint region.
  • Implementation of a upconversion spectrometer in an electronically controlled XY scanning unit forming a hyperspectral imaging plat form in the 6-10 µm range for wet bio samples.
  • Investigation of hyperspectral imaging for wet bio samples in terms of diagnostics content and specifically answering the question of how thick bio samples that can be used.

As a postdoc, you may be also involved in teaching for a period of up to one month. Experiments will be conducted with a suite of capabilities available at DTU or in collaboration with external partners.

This project is funded by a Lundbeck Experiment Grant.

Candidates should hold a PhD degree in Physics, Photonics Engineering or other science-related discipline. In addition, the candidates may have experience with two or more items listed below: 

  • Nonlinear optics.
  • Mid-IR spectroscopy.
  • Advanced data analysis.
  • Experience with experimental work.
  • Sound background/knowledge in optics is highly desired due to the photonics nature of the instrumentation.
  • Good communication skills in English (both written and oral) are required.
