Research Interests

My main research involves advanced diffusion NMR/MRI methods for probing microstructural features of tissues, such as cell size, shape, organization, cell-membrane permeability and microcirculation. I’m particularly interested in non-invasive multidimensional diffusion encoding approaches, which allow teasing apart different tissue features and thus provide highly specific information useful in research and in clinical applications. Within the C-MORPH project at DRCMR, I’m focusing mainly on time-dependent diffusion effects in tensor-valued encoding and exploring possibilities of using these effects to access novel microstructural information
