## Claire Guerrier, Ph.D

Postdoctoral fellow in the math department at UBC

Ph.D. in Applied Mathematics and Computational Biology under the supervision of Pr. D. Holcman.

Former student of École Normale Supérieure de Cachan.

Agrégée in Mathematics.

What please me the most in Mathematics is probably to understand how objects are working together. My preference goes most of the time to the constructive proofs of theorems. When I decided to work in neuroscience, I was motivated by the same idea: to use modelling and simulations to understand what are the key factors governing the phenomena observed experimentally. For this purpose, I develop mathematical models for neuronal structures to answer fundamental questions in neuroscience.

Emergence of spontaneous rhythmic patterns in the pre-Bötzinger Complex.

Building of a neuronal network model, that reproduces the oscillatory patterns observed in the pre-Bötzinger Complex, the neuronal network responsible for breathing at rest in mammals. This model predicts that oscillations that emerge at the network level are driven by synaptic properties of individual neurons. - Internship in the Biotechnology and Applied Pharmacology Institute of ENS Cachan (LBPA).
- June-july 2008, under the supervision of Marc Le Bret.

The conformal changes of proteins.

IComparison of different methods to determine the reaction path, in order to build an algorithm of lowest-energy that predicts the different conformations of a protein during a chemical reaction.

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.

Development and analysis of mathematical models, to determine how the properties of synapses at the molecular level shape their activity and propagate to the network level. I use several tools such as partial differential equations, stochastic processes and numerical simulations.
