BIOGRAPHY

L. Maaike Helmus received her PhD in forensic psychology at Carleton University. She is a co-founder and current Vice-President (Research) for the non-profit organization SAARNA (). Her research focuses on offender risk assessment, with the overall goal of improving the accuracy, fairness, reliability, and transparency of case management decisions made throughout the criminal legal system.

Helmus has a particular interest in risk scale development and validation, risk communication, and biases in decision-making. She has focused her research on men who have committed sexual offences or intimate partner violence, as well as exploring the cross-cultural applicability of risk factors and scales. Helmus also enjoys conducting meta-analyses. She is currently co-editor of the journal Sexual Offending Theory, Research, and Prevention and on the editorial board of Sexual Abuse.
