About Juan

I am an Associate Professor in the Department of Biostatistics and Bioinformatics in the Milken Institute School of Public Health at The George Washington University, Washington DC.

Online Courses

YouTube Lectures




For my work in the development of educational resources I was privileged to be recognised by the Open Education Consortiumas Educator of the Year in 2014.

Examples of my passion for training program development are my three successful courses on the world’s leading Massive Open Online Course (MOOC) platform, Coursera.  My course on Understanding Healthcare Statistics is ranked No.1 in its category on Class Central, the definitive repository on Open Courseware and has been ranked in the top 50 of all courses in the world for the last three years.

In support of these three very successful examples, I have created four additional courses on the popular Udemy platform, training healthcare workers on a variety of statistical and mathematical software packages. In addition to this I have published more than 1,400 lectures on YouTube and most of my open-source code is available on the GitHub repository.
