About the Author
Artificial intelligence is already reshaping healthcare. Yet most professionals still lack a clear, practical guide to what AI can do today, where its limits are, and how to implement it responsibly.
AI for Healthcare bridges the gap between technical possibility and clinical reality. It explains machine learning, large language models and AI agents through concrete clinical examples, then follows them into hospitals around the world where they are already in use.
Three parts: Fundamentals, Real-World Applications, and Responsible Implementation. Each chapter is enriched with exclusive interviews with physician-researchers and technology leaders from Stanford, Harvard, MIT and beyond.
“Artificial Intelligence. These two words spark passionate reactions. For some, they promise a brighter future in which diseases can be conquered. For others, they represent a threat, signaling the end of medicine as we know it. As is often the case, the truth lies somewhere in between.
Through this book, my goal is to provide a clear, balanced perspective on AI in healthcare, grounded in real-world applications, so that everyone can better understand its potential and benefit from the opportunities it creates.”
— Thomas Klein
Thomas Klein is an artificial intelligence expert and technology leader at Microsoft. Based in the United States, he works with major organizations on their digital transformation and strategic adoption of AI, with particular expertise in healthcare innovation, responsible AI, and the intersection of technology and human well-being.
A graduate of Télécom Nancy, a French engineering school specializing in computer science and telecommunications, Thomas also studied at the University of Leicester in the United Kingdom. He further developed his expertise through executive education programs in artificial intelligence at MIT and Harvard University, building on years of hands-on experience delivering innovative technology solutions in hospitals and healthcare organizations.
He began his career as a consultant, contributing to major digital transformation initiatives for the French government. He subsequently served as Director of Digital Transformation, leading projects for European institutions and developing extensive experience in technology strategy, organizational transformation, and large-scale innovation.
His commitment to applying technology for meaningful human impact was demonstrated through the implementation of a pioneering solution combining mixed reality and artificial intelligence to help children with autism develop their social skills. This initiative reflects his longstanding belief that technological innovation should directly contribute to human well-being, accessibility, and inclusion.
Thomas joined Microsoft France in 2020, where he helped organizations navigate complex digital transformations and accelerate their adoption of emerging technologies. His achievements earned him several distinctions, including Microsoft's Platinum Award and Technology Solution Excellence Award. He has also shared his perspectives on artificial intelligence in healthcare at HIMSS, one of the world's leading conferences dedicated to healthcare innovation and technology.
Beyond his corporate responsibilities, Thomas served as a city councilor in Suresnes, France, with a special responsibility for Responsible Artificial Intelligence. In this pioneering public-sector role, he championed the responsible integration of AI into local government services and organized the inaugural AI and My City symposium. This experience strengthened his understanding of the ethical, societal, and practical challenges involved in making artificial intelligence accessible and trustworthy for all citizens.
Since relocating to the United States in 2024, Thomas has continued working with organizations on technology strategy, digital innovation, and responsible AI adoption. He also serves on the board of French Tech Atlanta, helping strengthen connections between the French and American technology ecosystems and fostering innovation, entrepreneurship, and international collaboration.
Throughout his career, Thomas has combined technological expertise, strategic leadership, and a commitment to responsible innovation. His experience across the private sector, public institutions, and healthcare organizations provides him with a distinctive perspective on the opportunities and challenges of artificial intelligence, particularly its potential to transform healthcare while preserving the essential role of human expertise and judgment.
At the heart of his work is a simple belief: the true measure of technological progress is not what technology can achieve, but how it improves people's lives.
