"My primary interest concerns how the brain "forgets" things, both accidentally and on purpose. I use neuroimaging techniques to examine brain activity as healthy volunteers try to remember or forget things in the laboratory. Specifically, my lab investigates human working memory (our “mental workspace” for accomplishing goals) and its interactions with other cognitive functions including perception, attention, and long-term memory. Our research uses novel psychological tests, neuroimaging (fMRI and EEG), advanced analysis methods, and computational modeling to characterize core features of human cognition. Currently my research program focuses on three main threads: 1) long-term consequences of working memory operations, 2) removal of unwanted information from working memory, and 3) protection of working memory from distraction."

🦚 Postdoctoral Researchers

Dr. Laura Werner

Postdoctoral Research Fellow

Ph.D., University of Nevada, Las Vegas

📩 laura.werner@utexas.edu

"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

Ph.D., University of California San Diego

📩 dianejwhitmer@utexas.edu

"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."

"Motor deficits, such as the ability to individuate finger movements, is a common impairment associated with stroke that often never reaches full recovery. Here, we use hyperalignment to create a neural template of ideal brain activity from healthy participants. Our goal is to use this template to guide recovery in a real-time fMRI neurofeedback experiment post-stroke."

Zachary Bretton

Ph.D. student, Neuroscience (Year 4)

B.A., Boston University

📩 zbretton@utexas.edu

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

Ziyao Zhang

Ph.D. student, Psychology (Year 2)

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 1)

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 1)

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."
