1. Theory of water-proton spin relaxation in complex biological systems
Abstract : In complex biological systems (e.g. gels, cross-linked proteins and biological tissues), the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings. READ MORE

2. MRI evaluation and image processing in gel dosimetry. A study of selected MRI properties and image processing in 3D gel dosimetry
Abstract : Gel dosimetry is a new dosimetry method applied in radiation therapy. Gel dosimeters consist of a radiation sensitive gel, which can integrate absorbed doses from several radiation sources or beams. The dose to the gel can be evaluated by magnetic resonance imaging (MRI), a procedure that is the focus of the present thesis. READ MORE

3. Computational modeling of magnetic materials and alloys
Abstract : Magnetic materials play an important part in modern technology, appearing practically everywhere. Nonetheless, there is a need to discover new magnetic materials that can make devices faster, use less energy, and store more data. For this reason, computational modeling is an important tool.
