Research Summary

My research focuses on the development of data acquisition and image reconstruction techniques for magnetic resonance imaging, mostly in the brain, at 3T and 7T magnetic field strengths. My group works on pulse sequences and k-space sampling trajectories for fMRI, and methods for MR image reconstruction of highly accelerated data using sparse, low-rank and spatio-temporal constraints. While my main area of interest is fMRI, I am also involved in angiography and perfusion imaging using ASL, spectroscopic imaging, vocal-tract real-time MRI, and multi-modal imaging (simultaneous EEG+fMRI).
