Post-Doctoral position in Image Reconstruction/ Digital Holography 2010

A post-doctoral research fellow position is available at the Laboratoire Hubert Curien (LaHC), University of Lyon (Saint Etienne, France). The researcher will be integrated in the Image Reconsctruction team, run by Pr. Rolf Clackdoyle, as a member of the Digital Holography project led by Dr Corinne Fournier.

Digital holography is a time-resolved 3D imaging technique that is quickly evolving. This technique is the method of choice for 3D+t reconstruction of micro-objects spread in a volume. It has applications ranging from biology to fluid mechanics.

The main objective of this work is to improve the reconstructed 3D images (resolution and field of view) in digital holography. The approach will be built on an “inverse problems” framework we recently proposed ([1][2][3]).The developed algorithms will be applied to experimental data: digital microscopy holograms of biological samples and holograms of microparticles in turbulence.

Candidates should have a solid background in image analysis and applied mathematics and hold a PhD in Computer Science/ Signal and Image processing or a related field. Strong programming experience is required (e.g. C or Matlab). Previous experience in optimisation applied to image reconstruction (e.g. iterative algorithms for deconvolution, tomography) would be an advantage. Good writing skills in English are also required.

The candidate should be determined, enthusiastic, communicative, and able to work in a team.

Keywords: image processing, reconstruction, deconvolution, sparsity, microscopy.
