SIEF supports John Stocker Postgraduate Scholar to study low template DNA profiling for forensic human identification
Traces of DNA profiles in fingerprints are frequently too small to be of any value to forensic researchers because a high percentage of DNA is often lost through standard extraction procedures.
A SIEF John Stocker Postgraduate Scholarship supported Dr Jennifer Templeton, to identify a methodology – direct polymerase chain reaction (‘direct PCR’) – capable of obtaining DNA profiles from finger marks on a variety of substrates including wood, glass and metal. The method was shown to be reliable and reproducible, with a faster turnaround, reduced contamination, and higher success rate in meeting standards required for uploading data to the Australian DNA Database than standard methods.
The research was a successful collaboration between Flinders University and Forensic Science South Australia. Dr Templeton was supervised by Forensic Science expert Professor Adrian Linacre at Flinders University.
The outcomes of this project will have important projected impacts, including:
- Offering a methodology that is more reliable, robust, and reproducible; thus, reducing error rates and improving the efficiency of a variety of forensic analysis resources.
- Supporting the career development of Dr Jennifer Templeton, a Australian early career researcher, in the field of forensic science; as well as providing training in science communication and publishing.
