1. DNA strand exchange and hydrophobic interactions between biomolecules
Abstract : The role of hydrophobic interactions in DNA strand exchange has been studied using fluorescence-labeled DNA oligomers in a FRET assay. Strand exchange was found to be accelerated in the presence of polyethylene glycol, which provides a crowded and hydrophobic environment possibly mimicking that of the catalytically active recombinase-DNA complexes.

2. Electronic structure and exchange interactions from ab initio theory : New perspectives and implementations
Abstract : In this thesis, the magnetic properties of several materials were investigated using first principle calculations. The ab initio method named real space linear muffin-tin orbitals atomic sphere approximation (RS-LMTO-ASA) was used to calculate the electronic structure and magnetic properties of bulk systems, surface and nanostructures adsorbed on surfaces.

3. Modulating magnetic interactions : in metamaterials and amorphous alloys
Abstract : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. READ MORE

4. Modelling biomolecular interactions
Abstract : Computational approaches for understanding and aiding in molecular biology has increased in significance over the last decades, where a wealth of biochemical experiments have provided a solid ground for developing computer models that can be used to predict unresolved issues within biology. Molecular dynamics (MD) is one of these methods, based on classical laws, and suitable for handling large macromolecules in their natural environment, water. READ MORE

5. Learning from Interactions : Forward and Inverse Decision-Making for Autonomous Dynamical Systems
Abstract : Decision-making is the mechanism of using available information to generate solutions to given problems by forming preferences, beliefs, and selecting courses of action amongst several alternatives. In this thesis, we study the mechanisms that generate behavior (the forward problem) and how their characteristics can explain observed behavior (the inverse problem). READ MORE
