About Me

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.

I am also interested in research synthesis, meta-analysis and improving scientific practice (E.g. by promoting the principles of open science).

Influencing Behavior


I am interested in a number of different influences on applied decision making, especially within security and legal contexts. I enjoy taking multi-disciplinary approaches. I am also interested in methods of research synthesis and meta-analysis, and open science. Current and past projects have explored the following topic areas:

Suspect influencing behaviours within investigative interviews.
Insider threat detection via use of language.
Non-verbal signals and non-conscious processing in trust judgments.
Unlawful online file sharing and risk assessment.
Adherence to medicines in chronic illness.
The effects of pre-natal androgen exposure on sexual dimorphism and aggression.
