Victoria P. M. Lister, PhD, is a Lecturer in Forensic Psychology at the University of Lincoln.

She completed her PhD at the University of Kent under the supervision of Professor Theresa Gannon and Dr. Caoite O Ciardha, developing the first offence pathway model for voyeuristic behavior.
Her work has been presented internationally across the UK, Europe, Australia, the Phillipines, and North America, inlcuding at ATSA and IATSO conferences. She has received multiple awards for her contributions to the field, inlcuding the IATSO Poster Award and the ATSA Fay Honey Knopp Scholarship. Dr. Lister is passionate about briding research and practice to improve understanding, assessment, and professional responses to paraphilic and sexually harmful behaviors.
Elizabeth Deehan, PhD received her Bachelor of Science and Master of Science from the University of Lincoln in 2015 and 2017 respectively. She began conducting empirical research into somnophilia in 2016 as part of her Master of Science degree and continued this focus into her PhD, achieved in 2024 at the University of Lincoln.
