Claire Guerrier
Visiting scholar, McGill University - CRM CNRS researcher at Université Côte d'Azur Ph.D, Applied Mathematics and Computational Biology.
I am an applied mathematician working in computational neuroscience. My research focuses on studying multi-scale dynamics in neurons. From synapses to neural networks, I am doing modeling and analysis of systems with multiple time and space scales, that combine continuum dynamics with stochastic effects. The main theme I am developing concerns the function of the elaborate morphology of the dendritic tree in collecting, processing and disseminating information.
Keywords: Modeling in neuroscience, Computational biology, multi-scale modeling, PDEs, stochastic processes, Brownian simulations.

- 2016 - 2019, under the supervision of Prs. Dan Coombs and Kurt Haas, in the mathematics department and the Brain Research Center. Experience-driven neural encoding Modeling calcium dynamic in Xenopus tadpoles brain neurons in response to controlled visual stimuli, to study their impact on the growing and the morphology of the neurons. The final goal is to better understand how neurons process information, and improve or shift their encoding in response to experience.
