About
Pinel Baudelaire DAHOUI
I help companies, institutions and researchers get clear answers from their data. Alongside, I do research on trustworthy AI, blockchain and digital twins.
My story
I am a statistician by training. After a bachelor's in econometrics and applied statistics at the University of Abomey-Calavi, I completed the Master's in Mathematics, Economics and Statistics at the African School of Economics, then the Master's in mathematical statistics applied to life sciences at CIPMA – UNESCO Chair.
Since 2021, I have applied these methods to concrete projects: analyses for companies and NGOs, statistical studies for research, thesis supervision and field data collection. My work spans health, finance, agriculture and the environment.
My conviction: mathematics, data and algorithms are not reserved for a few. They should serve our problems, on our continent. That is also why I share what I learn through science outreach articles.
My approach
Three principles guide my work
Statistical rigour
Methods suited to the data, checked assumptions, explained uncertainty. A good model is first of all a model whose limits you know.
Useful results
Every analysis answers a precise question and leads to a decision. Deliverables are documented, reproducible and understandable by your teams.
Sharing knowledge
Training, thesis supervision since 2021, outreach articles: making science accessible is part of my job.
