About Us
We are field epidemiologists with R expertise, supporting frontline public health with access to versatile analytical tools and robust epidemiological methods. We are the home of The Epidemiologist R Handbook, used 1.2 million times by 350,000 people. We deliver practical R training courses to hundreds of health agencies and NGOs worldwide. We host Applied Epi Community - a Q&A forum for R code and public health practice.

R IS THE CATALYST FOR CHANGE
Free. Efficient. Cutting-edge. For a Haitian epidemiologist, using our free Epi R Handbook to transition routine analyses to R meant more flexibility, confidence, and time for systemic change.
‘With R I can do anything. What took 10 hours in Excel, I do in less than 1 hour. Also it is easier to detect if there is a mistake.’
Not just a new tool, but a new culture.In open-source software like R, users have the agency to be creators - to share localized solutions. Innovation is decentralised and career pathways are opened.
For Applied Epi, R is just the beginning. Adoption of R as the free common analytical language will facilitate higher-quality analyses, interoperability between agencies, reproducibility, overdue investment in ground-level personnel, and standardisation of scientific methods and training.
