Title: Human semen and DNA recovery from dog fur and organs over time under varying temperatures: Investigating stability in animal sexual abuse cases. 

Supervisors: A/Prof Laura Heathfield & Dr Calvin Mole. 

Thesis description: Animal sexual abuse (ASA) is an underreported crime that presents complex forensic challenges. Unlike human sexual assault investigations, there is very limited empirical data on the presence of human semen and DNA on or within the animal bodies. This lack of research restricts the interpretation of forensic findings and weakens evidentiary support in court. This study investigates how long human semen and DNA can be detected on dog fur and in vaginal and anal tissues under different temperature conditions over a 28-day period. By simulating forensic case scenarios, the research evaluates DNA degradation patterns and detectability of human biological material on animal samples. In addition, a national survey of veterinarians examines their awareness, experiences, and reporting practices related to ASA, identifying gaps in knowledge and procedural guidance. Together, this research aims to strengthen forensic methodologies, improve evidence interpretation, and enhance professional responses to cases of animal sexual abuse.
