Emma Johnston is an experienced forensic scientist with a strong background in DNA profiling and international experience. Having worked for one of the largest forensic science providers in the UK she has experience in examining items for DNA evidence, DNA extraction, PCR and capillary electrophoresis. Emma has prepared numerous DNA statements for the criminal justice system and presented DNA evidence in court on a number of occasions.

Emma spent two years working with the Department of Forensic Genetics at the Forensic Anthropology Foundation of Guatemala, where she gained experience of the application of forensic science to human rights investigations. In Guatemala, Emma delivered a number of research and development projects related to DNA profiling from degraded skeletal remains.

Emma carried out her doctoral research into the role of forensic science in the identification of missing migrants. She is currently involved in the ESRC-funded project "Trust in Forensic Science Evidence in the criminal justice system: The experience of marginalised groups".
