Research Summary

I bring the wealth of modern analytical tools from theoretical physics in order to quantify and interpret a variety of MRI modalities in terms of tissue structure below the nominal imaging resolution. I focus on MRI measurements of diffusion, transverse relaxation and perfusion, in order to quantify biophysical parameters such as cell structure and size, membrane permeability, amount of accumulated iron, etc, and to identify quantitative disease biomarkers in neurodegenerative diseases, tumors and myopathies.
