Broadly, I am interested in understanding how we encode, represent, and retrieve past events from visual working and long-term memory. Using a combination of behavioral assessments and computational approaches, my work examines the cognitive processes that underlie memory and the mechanisms that contribute to performance.
More specifically, I seek to address questions such as:
1.) how do we reconstruct past events from memory while minimizing cognitive effort and error?
2.) how do we leverage our existing knowledge and expectations about the world to help fill in our fuzzy memories?
3.) what does the process of integrating real-world knowledge and memory look like across cultural groups, developmental groups, and as a function of expertise?
4.) and finally, how does the context of study information govern what we recall about the past?
