Statistical Consultant
Expert Consultation for Your Statistical Studies and Data
I’m Justin Belair – an international expert on data science and statistics. My statistical consulting and freelance work help dozens of both academic and industry researchers from all over the world understand their data.
Many of my collaborations get published in top peer-reviewed journals, and I help clients solve important R&D problems to optimize Return-On-Investment of their innovative products.
Based in Montreal, Canada, I offer a fully bilingual (French and English) statistical consultant service all around the globe.

Your Challenges = My Solutions
Statistical concepts and methodology can be overwhelming. It need not be that way!
Here are common challenges I’ve observed, and the solutions I provide.
With more than 10 years of experience teaching at the University level, building training and workshops in industry, and providing individual mentoring and tutorship, I can design custom training programs and workshops to bring your team to the next level.
It feels good to have an expert in your corner. In a few hours, I can validate the statistical analyses that your team or your CRO provide, giving you confidence as a decision-maker.
You have a project in mind and are wondering if there are data–internally or externally–that can answer your specific questions? I can help.
Our first free consultation will explore your project, identifying any questions or challenges. Then, you receive a customized proposal with the statistical tools that meet your project’s unique needs.
Receive guidance through the selection of appropriate outcomes/endpoints, statistical methods and sample sizes. Enhance the credibility of your project and increase its chances of securing funding and/or receive regulator buy-in.
Assure no negative feedback from reviewers and receive assistance in effectively addressing their inquiries. Increase the chanced of publication in higher Impact Factor (IF) journals. I’m a paper referee myself, so I know the high standards you must meet.
Together, we can design experiments that bring concrete results, helping you balance scientific rigor and cost.
Don’t worry about analyzing and cleaning huge real-world datasets—I love writing automated scripts to do big data
Choosing methods for complex confounding patterns in the data is a team effort: you, the subject-matter expert, and I, the statistician, can leverage modern causal inference tools (quasi-experiments, propensity score methods, sensitivity analyses, etc.) to understand robust cause-and-effect relationships, yielding insights into the predictable effects of your decisions and actions
There is a rapidly emerging trend to incorporate causality based-principles in machine learning and AI models. Using a predictive models relies solely on correlations, but my expertise can show you how to teach the model about the cause-and-effect relationships in the data that to overcome the “correlation is not equal to causation” conundrum.
Sometimes, it just feels good to go over questions with a professional. Fill out a contact form saying you need Immediate Help and your request will be promptly addressed.
