Job Openings

We regularly have openings for Ph.D. and postdoc positions, please contact me for further information.

We can offer a range of projects for dedicated and motivated students at both bachelor and master level. The projects are in general tailored to individual wishes.

In the news:

30/09/2010 our article on image transmission through an opaque material featured in the Research Highlight section of the journal Nature.

09/03/2010 our article on the measurement of the transmission matrix, highlighted in "Physics" here. Our work has also made the news in New Scientist (here), national geographic (here), in the french edition of scientific american (in french) and on the website of the CNRS (in french)

19/10/2010 in french : Experimental talk on "seeing in the eye, the revolution of the images of the retina" (here)
