Dan Chaltiel

Programming enthusiast, I'm a huge fan of R (tidyverse FTW!) for data analysis and data visualization. I also love Python for ML and scripting and Java/Kotlin for Android development. I can also like a bit of PHP and Javascript on full moon nights.

I am Pharm.D. and Ph.D. in epidemiology and I currently work as a biostatistician in clinical research.
