My research investigates the cognitive control functions that enable flexible and intelligent behavior. There are two key themes captured in my research program. First, given the centrality of cognitive control to many domains of cognition, my research aims to study flexible control as it manifests in many different contexts, ranging from visual attention to decision-making to memory. This approach can identify analogous functions of cognitive control across cognitive domains by leveraging theories and models that have been developed in one domain and then extending them to account for control functions in a separate related domain.
Second, I aim to address cognitive control across levels of analysis by connecting behavioral and brain data with theory-driven computational models that are rooted in neurobiological mechanisms. To this end, my research combines a variety of cognitive neuroscience techniques (fMRI, EEG, TMS) with a range of modeling approaches (e.g. reinforcement learning, drift diffusion models, forward-encoding models, mathematical models of working memory) to test hypotheses about the computational and neural mechanisms underlying cognition.
