With over 190 publications (H-Index 54, with over 10,000 citations), her research as a Fellow of the British Psychological Society and as a Chartered Forensic Psychologist has concerned the best ways to access reliable testimony, especially from those deemed most vulnerable, by developing novel communication techniques. Jointly with practitioners, she has helped to create procedures that improve the quality of interviews of witnesses, victims, intelligence sources, and suspects.

She works closely with the police (and other criminal justice organisations), creating practical solutions based on research, developing training, running interview courses, co-writing National Guidance (e.g. The Achieving Best Evidence Guidance, MoJ) and providing case advice (e.g. London Bridge terror attacks, War Crimes Team, Southport case, Sarah Everard case). She is the Founder and Director of the Centre of Forensic Interviewing, an internationally recognised centre of excellence.
She is Editor in Chief of the International Journal of Police Science and Management. She was given the Tom Williamson award for her outstanding achievements in the field of investigative interviewing by NPCC in April 2009. In 2020 she was the sole awardee of the British Psychology Society Award for Excellence in Forensic Psychology Research. She is the UK MC Representative for the European Cooperation in Science and Technology (COST) project- Establishing Networks to Implement the Mendez Principles.
