Analysing the distribution of gunshot residue (GSR) on clothing and developing new approaches to the identification and classification of GSR from forensic samples.
Decrease in the use of GSR in criminal investigations: In recent years, the use of gunshot residue has decreased in criminal investigations due to the increase use of DNA evidence and the lack of understanding into its behaviour. Therefore, my research project is focusing on analysing the distribution of gunshot residue (GSR) on clothing of witnesses in addition to analysing the perspectives of the court on the use of experimental case studies to assist with expert testimony.

Interpretation of GSR particulates in particular contexts: This project would be beneficial for the forensic community as it can provide research into analysis protocols for GSR. If a clear distribution pattern is determined from this project then this methodology would be valuable for the crime reconstruction process, and the effective interpretation of GSR particulates in particular contexts.

Forensic science in the courtroom: Additionally, the research will help assist with the communication between forensic scientists and the court by gaining an insight into the opinion of each aspect of the court room which will assist with providing more robust testimony in court and gain a deeper understanding of what is expected from the forensic scientist in court.
