1. DNA Analysis of PCR-Inhibitory Forensic Samples
Abstract : DNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. READ MORE

2. Assesing performance of PCR analysis using Bayesian modelling
Abstract : Different analytical methods are available to analyse the DNA samples from crime scenes or to screen samples for the presence of some target bacterium. For this purpose a method known as Polymerase Chain Reaction (PCR) can often be used. READ MORE

3. PCR inhibition mechanisms in forensic DNA analysis
Abstract : In forensic DNA analysis, the polymerase chain reaction (PCR) enables DNAanalysis of minute biological crime scene traces. PCR is an enzymatic reaction for amplification of specific DNA fragments involving both biochemical andbiophysical processes. The main analytical challenge is posed by the nature of the samples of interest. READ MORE

4. Bayesian inference for detection problems in biology
Abstract : This thesis is about different kinds of detection problems in biology: detection of DNA sequences in crime scene samples, detection of harmful bacteria in feed and food stuff and detection of epidemical diseases in animal populations. In each case, biological data is produced or collected in order to determine which DNA sequences, bacteria types or diseases are present, if any. READ MORE

5. The Role of Chlamydophila Pneumoniae in the Inflammatory Response and Expansion of Abdominal Aortic Aneurysms
Abstract : Abdominal aortic aneurysm (AAA) is a common disease that develops gradually over several years and is characterised by weakening and dilatation of the aortic wall. AAAs also demonstrates a marked inflammatory infiltrate throughout the aortic wall. Chlamydophila pneumoniae (C. pneumoniae), is a common bacterium. READ MORE
