Synopsis:

My primary research interests are in improving magnetic resonance imaging (MRI) using signal processing and inverse problems techniques. In MRI, my focus is on accelerated imaging, image reconstruction and sampling problems, with an interest in novel pulse sequences. In signal processing, I focus on theoretical analysis and algorithms for inference problems that exploit low-dimensional structures in big data.
