Why Work With Me For Your Epidemiology Needs?

Working with a specialist provides distinct advantages for your research success.

Time Efficiency

Focus on clinical interpretation while I handle complex statistical challenges.

Methodological Rigor

Apply established epidemiological principles with modern analytical approaches.

Accurate Results

Use appropriate methods that account for study design, confounding, and population characteristics.

Publication-Ready Output

Receive results that meet journal standards and regulatory requirements for epidemiological research.

The Epidemiology Consulting Process

My consulting approach ensures methodological soundness and practical applicability.

Initial Assessment

We discuss your research questions, available data sources, study population, and specific epidemiological objectives during our discovery call.

Study Protocol Development

Together, we establish the study design, define key variables, select appropriate analytical methods, and create a detailed project timeline with clear deliverables.

Data Analysis & Implementation

I conduct the epidemiological analysis using established methods, handling complex issues like confounding, selection bias, missing data, measurement error, and timing issues (immortal time bias) and appropriate statistical modeling.

Results & Documentation

You receive comprehensive reports with epidemiologically-appropriate tables, figures, methodology documentation, and interpretation guidelines for your specific research context.

Need epidemiological expertise?
From study design to complex population health analyses, I provide specialized knowledge and hands-on analysis. Together, we can advance your research and public health impact.

Case Studies

I worked on large medical datasets to answer causal questions related to epidemiological determinants of disease through complex exposures. Challenges included selection bias, confounding, and missing data. I successfully developed a strategy that gave researchers confidence in their results.
I’ve worked with R&D scientists who were simultaneously running multiple experiments to answer important questions about their cutting-edge products that would have a direct impact on various stakeholders. My role was to help in designing and analyzing the experiments, balancing the conceptual purity of the Design of Experiments theory (DoE) with pragmatic concerns relating to costs and timeline. Most of this work is sealed behind a Non-Disclosure Agreement (NDA) which prevents me from elaborating more.

Don’t Just Take My Word For It…

The positive experiences of my happy collaborators showcased through their glowing testimonials, serve as powerful proof of trustworthiness and the impact of the results I deliver. These testimonials offer real-life examples of how I’ve helped research projects succeed. Here are some of their thoughts:

5/5

"He has a deep understanding of statistics, yet is able to skillfully explain complex concepts to people with little-to-no background in statistics both in French and English."

Elsa Brunet-Ratnasginham

Post-doc, UCSF

5/5

"I had never before worked with a biostatistician who speaks the same language as me! [...] Personally, our collaboration has allowed me to reconcile with statistics."

Manon Nayrac

Post-doc, CRCHUM

5/5

"I highly recommend Justin and his team for your data processing needs in order to have a more robust statistical model than the tests we are accustomed to conducting as biologists!"

Gérémy Sannier

Ph.D candidate, CRCHUM

5/5

"Thanks to him, statistics appeared to me as solutions rather than obstacles."

Justin Belair - Causal Inference Expert

My Statistics and Causal Inference Expertise

As a university-level statistics lecturer with a substantial LinkedIn following, scientists from all over the world come to me for my unique combination of academic excellence and practical experience in statistics and causal inference.

I’ve applied causal inference methods in varied settings in both academia and industry: in biomedical sciences such as nephrology, immunology, neuroscience, virology, occupational therapy, epidemiology, dermatology, psychiatry, and oncology; in natural sciences such as agronomy, ecology, and zoology; and social sciences such as communication, and psychology. The list keeps on growing!

I am currently writing an advanced textbook that I hope will give a young generation of academic and industry researches the tools needed to grapple with the complexities of causal inference, and maybe even develop a passion for the subject!
