1. On the effects of surface roughness in lubrication
Abstract : Tribology is a multidisciplinary field defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication. A typical tribological application is the rolling element bearing. READ MORE

2. Rough surface elastohydrodynamic lubrication and contact mechanics
Abstract : In the field of tribology, there are numerous theoretical models that may be described mathematically in the form of integro-differential systems of equations. Some of these systems of equations are sufficiently well posed to allow for numerical solutions to be carried out resulting in accurate predictions. READ MORE

3. Antiadhesive agents targeting uropathogenic Escherichia coli : Multivariate studies of protein-protein and protein-carbohydrate interactions
Abstract : This thesis describes studies directed towards development of novel antiadhesive agents, with particular emphasis on compounds that prevent attachment of bacteria to a host-cell. Three different proteins involved in the assembly or function of adhesive pili in uropathogenic Escherichia coli have been targeted either by rational structure based design or statistical molecular methods.

4. Numerical models to simulate wear and friction-induced heating in rough surface contacts
Abstract : The study of friction and wear is a crucial element in the effort to reduce carbon footprint in technology. It is evident that friction and wear are responsible for a significant amount of global energy losses, emphasizing the need for research on the topic. READ MORE

5. Influence of surface roughness on rolling contact fatigue considering thermal elastohydrodynamic lubrication effects : Due to Corona it is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/0_omfsppe6
Abstract : Rolling contacts are utilized in many technical applications, both in bearings and in the contacts between gear teeth. These components are subjected to high loads in many of their applications. The high loads causes very high contact pressures which may cause rolling contact fatigue, often denoted as pitting or spalling. READ MORE
