GAIA
I’m an associate professor of Computer Science at Université Grenoble Alpes, teaching at IM2AG (UGA) and Ensimag (Grenoble INP).
I conduct my research within the GAIA team at GIPSA-lab. My research interests include Bayesian inference, statistical signal processing, probabilistic learning, multifractal analysis, and applications in medical imaging.
Biographie
I was a postdoctoral research associate at CREATIS and Université Claude Bernard Lyon 1 from 2023 to 2025.
