My primary interest concerns how the brain "forgets" things, both accidentally and on purpose. We use novel psychological tests and functional neuroimaging techniques (fMRI and EEG) to examine brain activity as people try to remember or forget things. Broadly, our research investigates human working memory (our “mental workspace”) and its interactions with other cognitive functions including perception, attention, and long-term memory. Currently my research program focuses on two main threads: 1) the removal of unwanted information from working memory, and 2) the protection of working memory information from distraction.

My overall research goal is to understand how working memory functions. I am particularly interested in understanding forgetting mechanisms in working memory, such as removal. My current research focuses on how emotional memories are removed from working memory.

Dr. Diane Whitmer

Senior Research Fellow

My overall research interest is neuromodulation of cognitive function via real-time closed-loop neurofeedback. In particular, I am interested in whether memory competition and subsequent forgetting can be facilitated by closed-loop neurofeedback.

📩 zbretton@utexas.edu

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.

Ziyao Zhang

Ph.D. student, Psychology (Year 3)

M.S., Lehigh University

📩 ziyaoz@utexas.edu

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.

Caleb Jerinic-Brodeur

Ph.D. student, Psychology (Year 2)

B.S., Arizona State University

📩 cjerinic@utexas.edu

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.

Edward Leung

Ph.D. student, Neuroscience (Year 2)

B.S., B.A., University of Washington

📩 edjoeleung@utexas.edu

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.
