About
I'm Mehdi Aoussat, UX Research Lead based in the Paris region. With 8 years of experience in user research, I help product teams transform insights into strategic decisions — from exploration to impact measurement.
My background in cognitive psychology gave me a solid scientific foundation that I apply daily: methodological rigour, statistical analysis, and a deep understanding of human decision-making mechanisms.
View my backgroundResearch as a decision lever
Research only has value if it drives decisions. I work to position UX insights at the heart of product governance.
Methodological rigour and pragmatism
Qualitative and quantitative methods aren't opposed — they complement each other. I choose the tool based on the question, not habit.
A scalable practice
Building a sustainable research infrastructure — panels, processes, repository — is just as important as conducting studies.
