About
Guillaume Lajoie’s research program seeks to understand and guide dynamics in neural networks. Rooted at the intersection of Applied Mathematics, Artificial Intelligence (AI) and Neuroscience, his work seeks to extract lessons from the brain to build artificial systems that learn better, and in turn, develop tools to interact with and uncover brain functions. By pursuing a range of complementary research topics, his goal is to establish synergetic advancements in the following two research axes: 1) biologically-inspired architectural inductive biases in shaping learning and dynamics in artificial neural networks; 2) development of AI tools for brain-machine interfacing with the goals of studying how the brain learns to inform AI, and to allow direct interaction between artificial and biological neural networks for clinical use.
