Alexandra Badea
Associate Professor in Radiology

My interest lies primarily in using MR microscopy to image the rodent brain, including its vasculature, so as to provide comprehensive morphometric phenotyping. I study the morphometry of the rodent brain, its anatomical variability in normal states, and also in human disease models. These studies require several steps: imaging protocols for optimal contrast, brain segmentation, registration, statistical analysis, and atlasing. Ultimately we should be able to quantify changes during normal development, aging, disease progression and to assess treatment effect in a quantitative fashion. By combining imaging data with behavioral and genetic tools we have a truly interdisciplinary approach in our translational studies.
