Harvey Castro keynote speaker

Harvey Castro, MD, MBA, widely known as DR GPT™, is a physician, entrepreneur, author, and one of the leading voices on the practical application of artificial intelligence in healthcare. A board-certified emergency physician with more than two decades of frontline clinical experience, Harvey brings a perspective that is increasingly rare in the AI conversation: he understands both the extraordinary potential of emerging technology and the realities of delivering care when human lives are at stake.

Unlike futurists who examine healthcare technology from a distance, Harvey continues to work clinically as an emergency physician. This experience shapes his fundamental approach to AI: technology must work not only in demonstrations and laboratories, but in the complex, high-pressure environments where physicians, nurses, and patients actually use it.

Harvey currently serves as Chief AI Officer at Phantom Space, where his work extends the possibilities of artificial intelligence beyond traditional healthcare environments and into applications involving space and astronaut health.

His journey into technology began long before the current generative AI revolution. A physician entrepreneur and former healthcare CEO, Harvey has built and led healthcare businesses, including eight freestanding emergency rooms, as well as physician staffing and medical billing operations. He has also developed more than 30 mobile applications, giving him firsthand experience of translating clinical problems into practical technology solutions.

With the emergence of ChatGPT and large language models, Harvey became an early and prominent advocate for exploring how generative AI could transform medicine. Under the DR GPT™ platform, he has built an extensive body of work examining how AI can support physicians, improve clinical workflows, enhance decision-making, empower patients, and reshape healthcare delivery.

But Harvey is equally focused on what can go wrong.

His work addresses AI hallucinations, automation bias, patient safety, privacy, clinical governance, algorithmic bias, and the danger of implementing technologies without sufficient physician involvement. His central message is that the future of medicine should not be AI replacing healthcare professionals—it should be AI combined with human judgment.

Harvey is also an accomplished author whose work explores AI in healthcare, emergency medicine, physician leadership, and the future of medicine. He has delivered five TEDx talks and made more than 100 live television appearances, developing a reputation for translating complicated developments in artificial intelligence into clear, engaging, and practical insights.

Today, Harvey advises healthcare leaders, boards, hospitals, innovators, and technology companies on responsible AI adoption. His work spans the journey from experimentation to implementation: identifying valuable applications, understanding risks, developing governance, integrating AI into clinical workflows, and ensuring that technology ultimately improves rather than complicates patient care.

As a keynote speaker, Harvey gives audiences a physician's view of the AI revolution—combining frontline medical experience, entrepreneurship, technology expertise, and an optimistic but pragmatic vision for the future of healthcare.
