Research Interests:
I am developing new magnetic resonance imaging (MRI) techniques to infer the sizes of micron-scale compartments, such as axon diameters, in samples. I am also developing high resolution multi-contrast methods to understand brain structure. Partnering with Cubresa, Inc, I am developing simultaneous positron emission tomography (PET)/MRI methods. Partnering with SCHI and SCHERI, I am developing a new intraoperative MRI system.
