I became a behavioral scientist because I wanted to understand something that felt both simple and deeply puzzling: why do smart, well-intentioned people still get it wrong? That question has shaped over a decade of research into human judgment, confidence, and decision-making — particularly in high-stakes environments where getting it wrong has real consequences.

Today, I'm a Postdoctoral Research Scientist at Iowa State University, where I lead a federally funded research program in partnership with the Department of Justice and the FBI's High-Value Detainee Interrogation Group. My work sits at the intersection of experimental psychology, behavioral assessment, and applied science — designing studies that are empirically sound and produce findings that stakeholders and practitioners can actually use.

I've led countless mixed-methods studies, conducted population-level meta-analyses, and built behavioral assessment tools now in active use by law enforcement. Before Iowa State, I worked as a researcher and program evaluator at the Ontario Provincial Police, examining how technology adoption changes organizational behavior. This work shaped countless national and provincial policies.

I hold a PhD in Forensic Psychology and an MA in Criminology from Ontario Tech University, and a BA Honours in Psychology from Carleton University. I've published in journals including Applied Cognitive Psychology, Law and Human Behavior, and Journal of Experimental Psychology: Applied, and have presented at 20+ national and international conferences.

Outside the lab, I care about making science legible — to stakeholders, to policymakers, to practitioners, to students, and to laypeople. If you're working on a problem at the intersection of human behavior and applied decision science, I'd love to connect.
