Mathieu Boudreau, PhD

MRI Physicist

I’m a research software developer specializing in medical imaging and open science. I build and maintain open-source scientific software used by medical imaging and neuroimaging labs around the world.

I’ve spent most of my career in MRI physics: first as a researcher, now mostly on the software side. I’m the lead maintainer of qMRLab, a quantitative MRI analysis toolbox adopted internationally, and of AxonDeepSeg, a deep learning tool for segmenting axons and myelin in histology images. I designed, built and shipped MR Studio on my own: a browser-based editor for building publication-quality MRI pulse sequence diagrams, written test-first in React and TypeScript.

A recurring thread in my work is reproducibility: I led an international reproducibility challenge on T₁ mapping with 30+ contributors across multiple sites, co-authored an extension to BIDS — a widely adopted community standard for organizing neuroimaging data — and have contributed to NeuroLibre, a platform for publishing fully reproducible research.

I also work on the communication side of science. I was the Deputy Editor for Scientific Outreach at Magnetic Resonance in Medicine for five years, and led the digital content team at MRM Highlights, interviewing researchers about new work and making it readable.
