Ila Fiete builds theoretical models and tools that are elucidating computations performed by the brain as it interacts with the world. Her focus includes describing how plasticity and development shape networks to perform computation and how the brain represents and manipulates information. She works closely with collaborators to design experiments that allow analysis of how the brain solves complex tasks, such as spatial navigation. By combining theoretical insights with predictions and designs for experiment, Fiete aims to better understand how the brain constructs and uses memory for spatial and non-spatial reasoning, the mechanisms for error control in neural codes, and rules for synaptic plasticity that enable neural circuit organization. Through these avenues, she hopes to better understand the circuits underlying phenomena including short-term memory, integration, and inference, navigation, and reasoning in the brain.
