Our group specializes in Magnetic Resonance Imaging (MRI). We develop technical solutions to generate high-quality images and advanced techniques, such as quantitative MRI and image processing tools for studying brain development and pathology. Our lab has access to a wide range of scanners, including a portable ultra-low field (https://hyperfine.io/swoop/overview) MRI scanner, a 3 T Siemens Magnetom Cima.X scanner (CHU Sainte-Justine) with 200 mT/m strength gradients, and a ultra-high field 7 T Magnetom Terra MRI (Montreal Neurological Institute). Our research is highly interdisciplinary, and we are open to students with a wide range of scientific backgrounds.
