I'm interested in how the brain forgets things, both accidentally and on purpose. In my lab, we use behavioral tests, neuroscience tools and computational techniques to study how human memory works.

My research centers on how the brain manipulates information to serve goal-directed behaviors. My projects explore: (1) how different cognitive strategies for removing thoughts from mind lead to changes in their memory representations; (2) if fMRI neurofeedback can help people to remove unwanted thoughts from mind; and (3) how manipulation of information in working memory impacts long-term memory.

I am intrigued by how we control and manipulate information in mind to navigate the complex worlds around us. My research focuses on understanding the neural mechanisms and behavioral impacts of removing information from working memory. By merging computational and cognitive neuroscience techniques, I explore the intricacies of our cognitive control systems and their impacts on our memory.

My main interest lies in the interaction between memory and attention. Specifically, I am interested in how attentional control shapes memory representations and how internal representations influence ongoing processes. My research combines cognitive neuroscience and computational techniques to explore these questions.

My main research interests revolve around the ability to control what we remember. More specifically, I’m curious as to how removal processes influence forgetting in the context of emotional information. I’m also interested in how these working memory mechanisms influence long-term memory outcomes.

I am interested in understanding the factors behind retrieval of long-term memories into working memory and how that affects behavior and decision making. Additionally, I want to explore retrieval in the context of psychological disorders such as PTSD or addiction, when maladaptive information dominates working memory processing.
