RESEARCH INTERESTS
Dr. Podorov's main research interests include X-ray diffraction theory, X-ray characterisation of semiconductor structures and high resolution X-ray imaging and spectroscopy. Currently, Dr. Podorov's research is focused:

• To develop a generalized theory of dynamical wide-angle X-ray scattering.
• To study multilayer semiconductor structures, containing quantum-size objects, by high resolution X-ray diffractometry.
• To develop methods of phase-contrast imaging.
