About

I am a senior leader in information technology, AI and IT Security. Please read my reflections on these topics on my blog: https://medium.com/@drrispens. I help organizations navigate the AI revolution (and the cyber risks connected to that) through a unique combination of deep AI technical expertise, enterprise security leadership, and philosophical training. With a PhD in the foundations of AI, CISSP and CISM certifications, and a background in philosophy of mind as well as computer science, I provide complete cyber, AI security and ethics advisory—from technical implementation to board-level governance to existential ethical questions. I laugh easily, and I like to make people laugh. This creates joy. Joy creates a strong foundation for contact. Contact makes it easier to discuss complex ideas and get a deeper understanding of the issues at hand. Joy allows us to stay longer with the problem. Humor is the litmus test of intelligence. It's the way toward high-performing teams and better solutions.
