I am Harvey Castro, MD, MBA, known as DR GPT™. I am a board-certified emergency physician who writes and speaks about artificial intelligence in medicine. Everything collected here comes out of the same work: clinical shifts, board rooms, conference stages, and the questions healthcare leaders keep asking me when the microphone is off.
This page pulls together articles, media appearances, talks, and published work in one place so you can see the thinking behind a keynote before you book one.
