KU Leuven

Postdoctoral position in non-linear optics and coherent raman microscopy

KU Leuven

Leuven, Belgium

The Roeffaers lab (http://www.roeffaers-lab.org) develops optical microscopy tools and assays to study catalyst properties and catalytic processes under realistic conditions and this at the smallest time and length scales possible. Currently, coherent Raman and pump-probe microscopy but also single molecule fluorescence microscopy, integrated electron-fluorescence microscopy are used.

Specific research line:

Current ambient outdoor air pollution concentrations are responsible for 3.7 million premature deaths worldwide. The combustion-related black carbon (BC), increases cardiovascular morbidity and mortality, but also chronic respiratory diseases and lung cancer. Although, the air pollution associations are established as causal, risks might be considerably underestimated due to exposure misclassification. Until now, in most epidemiological studies the exposure to PM air pollution is not measured at the level of individual persons. We recently developed optical techniques to detect BC in a label-free manner, which was previously not feasible. However, further research is required to distinguish individual types of particulates e.g. by integration of (simulated) Raman microspectroscopy and study different biopsy types (e.g. compositional variations, …).

Responsibilities
The main goal of this position is therefore the (further) development of sophisticated optical techniques to identify and classify PM. In particular, the project addresses the following questions:

  • Can we optically characterize the material composition and size of the particles? If yes, how fast and reliable can this be done?
  • Is this technique applicable to samples with medical and environmental relevance?

By applying advanced optical (micro)spectroscopy we aim to resolve these problems. You will be responsible to further update a multimodal non-linear optical microscope equipped with a femto- and three picosecond lasers coupled to an Olympus FV1000 microscope and multiple detectors that allows correlative coherent Raman scattering (stimulated Raman and coherent anti-Stokes Raman), SHG and multiphoton autofluorescence capabilities. You will work in a multidisciplinary environment in close collaboration with the groups of prof. Ameloot and prof. Nawrot from Hasselt University.

Profile

We are seeking highly motivated candidates that hold a PhD in chemistry, physics or nanotechnology related subjects. Experience with non-linear optics, characterization and optical microscopes is particularly required. The candidate should be open to interdisciplinary science and collaborations. KU Leuven offers in this respect an ideal environment with a large number of science groups working on different (applied) subjects. The university is one of Europe’s oldest academic institutions and is situated in a medium-sized vibrant student town with a large international community.

Offer

A 1 year postdoctoral position with possible extension with 1 or 2 more years.
