The project aims to aid in producing better procedures for the collection and assessment of eyewitness identification evidence. In a police line-up, a witness is asked to identify a perpetrator from a group of similar individuals. Applied research has focused on conditions that optimise witness performance but many of the conclusions from this research have been challenged on the basis that they use inappropriate measures of performance. Recent work has highlighted the usefulness of analyses based on the theory of signal detection. However, the line-up task does not fit easily within standard signal detection paradigms as it combines two tasks; detection and identification. The project aims to understand how these components work in order to measure witness performance.Read moreRead less
Who should join the suspect in a police photo array? The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the su ....Who should join the suspect in a police photo array? The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the suspect. However, the fillers are likely to have a crucial influence on decision accuracy. This project aims to remedy this striking deficiency by developing and testing a flexible and universally applicable methodology for photo array composition that will optimise judgmental discriminability and curtail bias.Read moreRead less

Improved interviewing framework in sexual assault cases. This project aims to provide a better interview framework to be used by police in the investigation and possible prosecution of sexual assault allegations. The current interview framework used around the world was not specifically designed for adult sexual assault complainants and has been intensely criticised. This project will design a revised interview framework that meets the complex investigative and evidential requirements for these ....Improved interviewing framework in sexual assault cases. This project aims to provide a better interview framework to be used by police in the investigation and possible prosecution of sexual assault allegations. The current interview framework used around the world was not specifically designed for adult sexual assault complainants and has been intensely criticised. This project will design a revised interview framework that meets the complex investigative and evidential requirements for these interviews. This is expected to increase just outcomes and victim satisfaction with the criminal justice response.Read moreRead less

Visualisation of latent DNA. This project aims to deliver a proof-of-concept that allows visualisation of invisible DNA (latent DNA) into a quick, inexpensive and practical DNA collection method that will lead to DNA evidence being available in more cases. It will build upon a proof-of-concept method ready for transferal to forensic casework. This will allow DNA evidence recovery technicians to improve their hit rate in recovering latent DNA from real crime items, leading to more informative DNA ....Visualisation of latent DNA.

It will build upon a proof-of-concept method ready for transferal to forensic casework. This will allow DNA evidence recovery technicians to improve their hit rate in recovering latent DNA from real crime items, leading to more informative DNA profiles. Crime items that currently yield no genetic information will now be informative, assisting investigations of serious crimes or terrorist incidents.Read moreRead less

Next-generation latent fingermark detection using functional nanomaterials. This project aims to develop a nanotechnology-based fingermark detection technique applicable in standard police laboratories and crime scenes. Current methods only detect half the fingermarks on an object, so many criminals are not identified. This project will use silicon oxide nanoparticles with a luminescent dye to target fingermark secretion components and address interference from substrate chemistries and background luminescence. Moving away from traditional detection methods is expected to improve law enforcement outcomes, as fingermarks that current technologies cannot detect will be visualised for the first time.Read moreRead less

Illicit drug profiling in forensic intelligence. This project aims to develop an optimised methodology that uses illicit drug profiling for operational intelligence. The fight against the illicit drug trade suffers from a relatively ineffective use of forensic science, predominantly applied as a reactive tool for court purposes after the commission of a crime, and a general under-utilisation of available information by Australian forensic drug laboratories whose scientific results contribute minimally to active operations. This project’s methodology, which uses forensic science proactively for intelligence rather than reactively for courts, is expected to make the fight against organised crime more effective and support the three pillars of the Australian National Drug Strategy (supply, demand and harm reduction).Read moreRead less
