13. Characterization of the MRI patient exposure environment and exposure assessment methods for magnetic fields in MRI scanners
Abstract : Magnetic resonance imaging (MRI) has become one of the most common imaging modalities available in modern medicine, and it is an indispensable diagnostic tool thanks to the unparalleled soft-tissue contrast and high image resolution. It is also a unique exposure environment consisting of a complex mix of magnetic fields. READ MORE

14. Pair production, vacuum birefringence and radiation reaction in strong field QED
Abstract : In this thesis we consider three QED phenomena in strong electromagnetic fields: Schwinger pair production, vacuum birefringence and radiation reaction. We study electron-positron pair production in a variety of field configurations and, using complex worldline instantons, reveal new insights into the case of fields with lightlike inhomogeneities.

15. Nonlinear interaction and propagation of gravitational and electromagnetic waves in plasmas
Abstract : Gravitational waves and electromagnetic waves are important as carriers of energy and information. This thesis is devoted to the study of the propagation and interaction of these waves in plasmas, with emphasis on nonlinear effects and applications within astrophysics. READ MORE
