6. Diagnosis of acute and chronic enteric fever using metabolomics
Abstract : Enteric (or typhoid) fever is a systemic infection mainly caused by Salmonella Typhi and Salmonella Paratyphi A. The disease is common in areas with poor water quality and insufficient sanitation. Humans are the only reservoir for transmission of the disease. READ MORE

7. Multivariate processing and modelling of hyphenated metabolite data
Abstract : One trend in the ‘omics’ sciences is the generation of increasing amounts of data, describing complex biological samples. To cope with this and facilitate progress towards reliable diagnostic tools, it is crucial to develop methods for extracting representative and predictive information. READ MORE

8. Maternal and neonatal metabolomes and their associations to immune maturation and allergy in early life
Abstract : Allergy, one of the most common chronic diseases worldwide, is caused by a dysregulated immune system reacting to normally harmless proteins. However, regulating mechanisms are not well understood. The aim of this thesis was to investigate if plasma and placenta metabolites associate prospectively to allergy development and immune maturation. READ MORE

9. New methods for determination of airborne pollutants : Focus on tetrabromobisphenol A, organophosphate triesters and polycyclic aromatic hydrocarbons
Abstract : The work presented in this thesis concerns the development and evaluation of new methods of sampling and analysis of organic pollutants in the indoor and outdoor environment. In Paper I, the development of a new method was reported for the determination of the brominated flame retardant tetrabromobisphenol A (TBBPA) in air using sampling with glass fiber filter and polyurethane foam (PUF), ultrasonic solvent extraction and liquid chromatography coupled to electrospray ionisation mass spectrometry (LC-ESI/MS).

10. Engineering synthetic pathways for adipic acid biosynthesis
Abstract : Utilization of petroleum in consumer product manufacturing is causing irreversible environmental damage. Its impact on land, sea, and air calls for the development of more sustainable technologies based on the use of renewable materials such as lignocellulosic biomass and its conversion into platform chemicals.
