Research Interests: I am broadly interested in understanding the neural and computational basis of flexible human cognition. My work addresses questions from a broad range of topics including fluid intelligence, working memory, learning & generalization, cognitive control, and social decision making, employing behavioral methods, functional MRI, computational modeling and machine learning. I’m currently investigating the role of neural representational geometry in enabling flexible cognition, with a particular focus on prefrontal cortex representations of task information.

Research Interests: I am interested in understanding the neural mechanisms underlying perceptual memory. In a collaborative project with “3D Information for Perception and Action Lab”, we aim to bring together two seemingly disconnected fields of research: 3D perception and visual working memory. We explore computational theories of visual perception incorporating psychophysical methods and fMRI.

Research Interests: I am interested in the dynamic process in which control-related representations are shaped to achieve flexible behavior. I hope to investigate how we generate and link abstract knowledge to specific action contexts in working memory.

Research Interests: I am interested in how the brain formats information as it guides difficult cognitive processes like multitasking. Using fMRI and behavioral data, I hope to create testable computational models that further our understanding of what enables the amazing flexibility of the human mind.

Research Interests: I am interested in how people adapt or transfer control policies learned from one context to another. I am using both neural and computational methods to investigate the underlying mechanisms that support the learning and adapting cognitive control.

Broadly, I am interested in human skill learning and how it is shaped by powerful biological constraints imposed by the human brain. I work on trying to understand how the human brain represents and responds to contextual learning/performance demands and how people benefit from training to address these demands. I am hopeful that tackling these issues can one day benefit educational experiences of others.
