Research interests
During my PhD studies supervised by Prof. Bogner I mainly worked on the clinical translation of high-resolution MR spectroscopic imaging. Particularly, I was interested in its application to multiple sclerosis brains, where high-resolution metabolic imaging of myo-inositol and N-acetyl aspartate allows to visualize focal and diffuse pathology in white matter which appears inconspicuous on clinical MRI and shows correlation with clinical disability status of patients.
As a postdoctoral researcher I continue to expand my interest in advanced multi-parametric MRI applications to a wider scope of demyelinating, neurodegenerative and rare inherited disorders, which hopefully contributes to their better understanding, diagnosis, monitoring and treatment.
