Research Interests: How are concepts structured to enable the generation of flexible, context-dependent representations? How is conceptual information manipulated in the brain such that an appropriate representation is formed?

Research in Progress: I have explored the flexible manipulation of conceptual representations in object-change, figurative language, and adjective-noun combinations. I am currently exploring the possibility of using network science approaches to model individual concepts, which might enable the quantitative modeling of conceptual flexibility and other phenomena.

Research Interests: I am interested in the cognitive and neural mechanisms of endogenous flexibility, the ability to adapt one’s behavior in the absence of explicit cues to do so. This ability requires the interaction of learning, decision-making, arousal, and cognitive control processes. Currently, I am studying endogenous flexibility in the domains of reinforcement learning and exploratory behavior. I have utilized a variety of methods in this work, including neuroimaging, pupillometry, noninvasive brain stimulation, genotyping, and computational modeling.

Research Interests: I study how and by what properties the brain leverages visual information in behaviors such as recognizing and categorizing objects and perceiving scenes. Using behavioral and neuroimaging methods with computational modeling, I aim to elucidate how certain ‘specialized’ layers of large-scale neural networks interact to give rise to visual perception and memory-related processes.
