Harvey Castro, MD, MBA. Physician Futurist | Chief AI Officer · Phantom Space | Building Human-Centered AI for Healthcare from Earth to Orbit | 5× TEDx Speaker | Author · 30+ Books | Advisor to Governments & Health Systems | #DrGPT™ Dallas-Fort Worth Metroplex Summary At 2 a.m. in the emergency room, seconds decide outcomes. Soon, those same decisions will be shaped by AI models, planetary-scale data, and infrastructure that lives beyond Earth.I'm Dr. Harvey Castro, ER physician, Chief AI Officer at Phantom Space, and the person connecting those two worlds.For over 20 years I treated crisis after it walked through the door. That experience burned one conviction into me: the future of healthcare isn't faster reactions. It's earlier signals.The problem health systems face today isn't lack of data. It's that the data lives in silos, the compute lives in buildings that flood and fail, and the AI lives in research papers that never reach the bedside.I'm working to fix that from orbit.At Phantom Space I lead AI strategy for space-based health infrastructure: orbital compute networks, satellite data pipelines, and edge inference tools that bring predictive intelligence to clinicians who need it most whether they're in Dallas or Djibouti.What this looks like in practice:Space-based compute that survives disasters and serves communities hospitals can't reach.AI that anticipates illness before it becomes crisis reducing burnout, protecting patient safety, and giving physicians back their judgment.Human-centered design that ensures the technology serves the clinician, not the other way around.I also advise health systems, governments, and regulators on how to deploy AI safely, ethically, and at scale without losing the humanity that medicine requires.The bottom line is simple.Compute in orbit. Care on Earth.If you are building the future of healthcare or trying to understand it. I would like to connect.
