I am a senior postdoc at the Department of Systems Neuroscience at the University Medical Center Hamburg-Eppendorf. My main research interests are:
  • Diffusion MRI: Modelling and correction of artefacts, sequence optimisation, bio-physical modelling of the diffusion signal (from macro- to micro-structure)
  • Structural MRI: Modelling and correction of artefacts, bio-physical modelling of MRI signal (proton density, myelin and iron content).
  • MRI reconstruction: Modelling and correction of artefacts (from k-space to image-space), bio-physical modelling of complex or k-space data (inter-changing image reconstruction and signal modelling)
I am currently working on high-resolution spinal-cord DTI, Kurtosis Diffusion Imaging, and their combination with multi-parameter mapping approaches.

Enabling activity

I am an author of the SPM toolbox: Artefact correction in Diffusion MRI (ACID toolbox). The ACID toolbox is an academic software toolkit for pre-processing of diffusion MRI data, estimation of DTI indices and spatial normalisation of DTI index maps. The main advantage of the ACID toolbox is the model-based approach to handling artefacts in diffusion MRI and thus in enabling high-end diffusion MRI applications. The ACID toolbox fully integrates into the batch system of the SPM package.
