I am interested in communicative aspects of investigations, and what this can reveal about the psychological mechanisms that underpin the behaviour of investigators, suspects and witnesses. My research covers legal and security contexts broadly, but with a particular interest in cybercrime and intimate partner violence.
I am also interested in research synthesis, meta-analysis and improving scientific practice, and engage in pedogeological research.

Organisations
I am interested in a number of different influences on applied decision making, especially within security and legal contexts. I embrace methodological diversity and my research uses quantitative, qualitative and research synthesis methods.
My primary research areas are police-civilian interactions (e.g. investigative interviews, human intelligence gathering and crisis negotiation), cybercrime, and intimate partner violence. I also conduct research into improving psychological research methods (e.g. via open science) and teaching, with a particular focus on promoting inclusivity.
I believe that applied research requires triangulation between the laboratory and field research and I particularly enjoy working with practitioners and the police. I am always welcome to approaches from academic and non-academic partners of diverse backgrounds to discuss whether we can help solve problems together.
