 Research Expertise & Professional Interests
Marc Howard, PhD, is a Professor in the Department of Psychological and Brain Sciences and member of the Center for Memory and Brain. He received his PhD from Brandeis University in Neuroscience. His research interests include: cognitive and neural representation of time and space; mathematical psychology; computational neuroscience; episodic and semantic memory; and reward learning and prediction.

About the Theoretical Cognitive Neuroscience Lab:
We develop mathematical models of cognition and evaluate them against both behavioral and neurophysiological data, providing a bridge between cognition and systems-level neuroscience. We use a combination of mathematical, computational and behavioral tools to evaluate our hypotheses. The topics we investigate are centered on episodic memory, the ability we have to remember specific events situated in a particular spatiotemporal context. At present, our efforts are focused on developing and evaluating a unified mathematical framework to describe how the brain constructs the spatial and temporal context believed to underlie episodic memory. This model appears to have far-ranging implications, leading to research interests in statistical learning, semantic memory, time perception, and reward systems.
