My research interest are X-ray phase-contrast imaging, X-ray micro- and nano-tomography, and wavefront sensing and optics characterisation.
X-ray phase-contrast imaging is a powerful method to access structures invisible with conventional absorption contrast. This method relies on the high sensitivity of the phase information, usually obtained through interference of the x-ray waves, to generate the image contrast. In this way details with small density differences, such as cancerous areas within healthy tissue, become clearly visible. At higher spatial resolutions, x-ray phase-contrast imaging provides unprecedented insight into the three-dimensional nanostructure of natural and manmade materials. These techniques are sophisticated methods requiring coherent and brilliant x-rays, and perform best at synchrotron facilities such as Diamond Light Source.
At beamline I13, I am implementing advanced x-ray phase-contrast imaging techniques, such as grating interferometry, speckle based imaging, and ptychography. These methods are applied to interesting problems mainly in the biomedical and materials science areas.
