The Medical Image Processing Lab (MIPLab) is headed by Dimitri Van De Ville. The lab is jointly between the University of Geneva (Faculty of Medicine, Department of Radiology) and the EPFL (School of Engineering, Institute of Bioengineering). Our research interests are at the interface between signal processing and medical imaging:
- Signal and image processing: wavelets, inverse problems, mathematical imaging, sparsity, pattern recognition.
- Functional imaging: (f)MRI, EEG, PET, laser Doppler optics.
We have regularly job openings
for post-doctoral fellows and PhD students.

We show scale-free behavior of EEG microstates in the range of 256ms-16sec, explaining the surprising link between fast EEG microstate changes and slow oscillations of resting-state fMRI. This study reveals the fractal organization of spontaneous brain activity as one of the underlying mechanisms of consciousness and cognition.
