Research Overview and Opportunities

My primary research interest centers on human memory processes and their real-world applications. My current work investigates eyewitness memory, suggestibility, source monitoring (how we identify the origins of our mental experiences), false memory formation, and the mechanisms underlying the acceptance of misinformation. These studies have direct implications for legal and clinical contexts, including evaluating eyewitness accuracy, investigating child abuse cases, and understanding jury decision-making.

My more recent research explores how individuals evaluate and accept misinformation, as well as the effects of technology—particularly artificial intelligence tools—on cognitive functioning and learning outcomes.

I typically have 2-3 undergraduate research assistant positions available each semester. Students newly joining the lab are expected to commit to at least two semesters of involvement. If you are interested in enrolling in PSYC 194 (Cooperative Research) or would like to learn more about research opportunities in my lab, please contact me.
