PhD : Development of coherent Stokes Raman scattering microscopy

Notre Mission : Our rent advances in coherent Raman microscopy allow for the real-time generation of artificially stained images of cancer samples which previously required time-consuming histopathological staining procedures. These images serve as feedback for surgeons to guide cancer surgery. As the main challenge, the examination of thick cancer samples is currently impossible, as all excitation light in coherent Raman microscopy is scattered forward and must pass through the sample. Within this project, you will develop a new coherent Raman technique called coherent Stokes Raman scattering (CSRS) microscopy. As the game-changer, CSRS will send the signal photons directly into the backward direction and, therefore, enable the investigation of thick, non-transparent cancer samples. Moreover, we will use CSRS’ backscattering property to record the CSRS spectrum of tissue at unprecedented speed levels using novel spectrometer concepts and multi-focus or wide-field illumination approaches. From these CSRS spectra, a precise diagnosis of the cancerous tissue will be derived by machine learning algorithm. Your mission is to set up and characterize these novel microscopy techniques and evaluate their functionality on cancer tissue.

Construction – You will build from scratch one or more new coherent Stokes Raman microscopes.
Simulation – You simulate your experiments in Matlab or Python. We work in close cooperation with theoretical physicists.
(Optional) experiments – You will examine cancer samples with your microscope and predict the malignancy of the tissue with the help of our machine learning experts at the institute.
