Ariane Lizotte

PhD student

Biography

I am PhD student advised by Antoine Allard and co-advised by Jean-Gabriel Young. I use Bayesian statistics and computational methods to improve our understanding of network models and properties. My current research focuses on the latent geometry of complex networks.
