Rene Andrade Rey

Physician & Neuroimaging Researcher

I build reproducible neuroimaging workflows across structural MRI, task and resting-state fMRI, diffusion MRI, MEG, EEG, and PET.

My work emphasizes transparent processing, quality control, cross-software validation, open science, and technically documented analysis pipelines.
