Presentation
My main research interest is x-ray and neutron-based 3D imaging of engineering materials, especially using diffraction-contrast techniques. I am particularly interested in developing and using methods that provide information about individual grains in polycrystalline samples, such as 3DXRD. I am also interested in more traditional x-ray and/or neutron tomography, especially when combined with in-situ manipulation of the specimen.
