Biography
Katrin Mueller-Johnson is Associate Professor of Criminology and a Research Fellow at Green Templeton College.
She holds a PhD in Human Development from Cornell University, a MSt in Legal Research from the Centre of Social Legal Studies, University of Oxford, and a Dipl. Psych. Degree in Psychology from the Free University of Berlin.
Her research interests are centred around victimisation, investigative interviewing and police as well as legal decision-making.
Within the area of victimisation her main concentration is on sexual offences, such as in child sexual abuse or rape. Her current research focuses on vicarious victimisation of police officers and police staff in the context of child abuse investigations. Her research into investigative interviewing is connected to this interest in sexual victimisation as in sexual offences there is often little evidence apart from the victim statement and thus the victim's testimony is of crucial importance. Dr Mueller-Johnson studies police interviewing of vulnerable witnesses, such as the investigative interviewing of children, older adults, or persons with disabilities. One major area of this research is on ways to improve the quality of police interviews. Her research on decision-making in the criminal justice context spans police as well as jury and judges' decision-making. Here projects have looked into differences in how potential jurors interpret the phrase “beyond reasonable doubt”, and into judges’ assessments of witness credibility.
Her work has been funded by the AHRC, ESRC, British Academy, Newton Trust, Optimus Foundation and Department of Justice for Northern Ireland. She has collaborated with UK and international police forces.
She teaches on the MSc in Criminology and Criminal Justice on Research Methods, Quantitative Data Analysis and Psychology, Law and Criminal Justice. She supervises DPhil, MPhil and MSc students in her areas of interest and particularly welcomes students who would like to work on areas of crimes against children or other vulnerable groups and well as those interested in legal psychological topics.
