Manuel Guizar-Sicairos is an Associate Professor of Physics in the School of Basic Sciences (SB), Institute of Physics (IPHYS), EPF Lausanne and head of the Computational X-ray Imaging group in PSI. His research is focused on developing methods and algorithms for computational imaging, in particular for large-scale synchrotron X-ray sources. For example for phase retrieval, X-ray coherent diffractive imaging, holography, ptychography, nanotomography, and scanning small angle X-ray scattering (sSAXS). His expertise encompasses experimental design, new imaging configurations or strategies, and devising novel reconstruction strategies. In particular he has co-developed 3D nanoscale imaging using ptychography, magnetization vector nanotomography, small-angle scattering tensor tomography (SASTT), and leveraging sparsity for hyperspectral and dynamic nanotomography. Applications of these techniques range from imaging of the brain at synaptic resolution, bone, catalysts, and 3D operando batteries.
