Research Interests

I'm an AI researcher interested in creativity, video-games, and open-endedness. In my research, I try to answer questions such as:
Many of my research contributions relate to the application of AI in video games. In particular, I have introduced new methods for the procedural generation of game content, human-like game playing, mixed-initiative design, and game adaptation based on models of player experience. But I have also developed AI methods for applications in areas as diverse as biometric security, oil field modeling, personnel selection, and music composition. While my primary algorithmic contributions are in evolutionary computation, especially quality-diversity search methods, I happily engage with algorithms from across the whole wide field of artificial intelligence. And while I'm pretty good at solutions, I'm great at problems; some of my main contributions to AI have been in defining new research problems and creating new, often game-based, research environments and benchmarks.
I write. Sometimes I write books, both technical textbooks and books meant to be accessible for a wider audience. I also write blog posts of varying quality. And (parts of) papers, of course.
I am the Head of AI for Nof1, where I lead a research team focused on AI for financial markets. It's more or less like playing video games. I am also a member of Unity's AI Council, and I co-founded modl.ai.
I believe AI should be complementary to human cognition and creativity, because I want human knowledge and creativity to continue to matter. How to make the various technologies we call artificial intelligence work for us rather than the other way around is the crucial question of our times. I don't know the answer, but I keep looking.
