Personal profile
Research Interests
As Assistant Professor in Research at the Department of Radiology of Northwestern University I am directing the 4D Lab. The 4D Lab is a new Radiology cardiovascular quantitative image analysis facility working on basic and advanced MRI data analysis to support research projects, multicenter studies or external collaboration partners. My personal research focus lies on the development and improvement of 4D Flow MRI sequences and image analysis methods especially for evaluating intracranial hemodynamics.
