Helen and I had the honour to talk to Dr. Luis Falcon, a Spanish computer scientist, physician (practising MD) and leader of the GNUHealth project. We spoke about health information ecosystems, medical management systems, wearable sensors, free software, privacy, community, and public health research. Dr. Falcon does a huge amount of very valuable and underappreciated work on systems that are extremely important in the world right now.
