Geographic Information Systems (GIS) and data visualization tutorials and lessons, with a focus on public health. Most videos posted here are for Master's students from courses at Carnegie Mellon University, Mount Sinai School of Medicine, and CUNY School of Public Health, Hunter College. Other core topics covered have come from my time working at 18F, the NYC Department of Health, Parsons Institute for Information Mapping. In many cases I include references and data used, which viewers can download directly to follow along. This channel is maintained "add-free" to provide a better user experience to my subscribers. All views are my own.
