Research Interests

My research reflects my passion for advancing our understanding of cognitive processes and human behavior. My research agenda is driven by a commitment to unraveling the complexities of memory, metacognition, social cognition, and their interplay. I specialize in utilizing behavioral methods and sophisticated modeling techniques to gain nuanced insights into these psychological phenomena.

My current research interest include:

• Source Memory and Source Guessing

• Prospective Memory

• Metacognition

• Schemas and Stereotypes

• Cheating and Cooperation

• Emotion and Memory during the COVID-19 Pandemic

• Continued Influence Effect of Misinformation 

• Mathematical Modeling, especially multinomial processing tree modeling and multi-level modeling
