Dr. Dirk Raiser is an experimental physicist with a strong analytical mindset and a deep passion for operating at the edge of technical and human performance. His work is driven by precision, curiosity and the ability to quickly understand complex systems - without losing sight of the bigger picture.

​

His professional approach combines scientific rigor with a hands-on, solution-oriented mentality. He works with a high level of responsibility and attention to detail, while remaining pragmatic, creative and focused on results. This balance between accuracy and execution defines both his engineering work and his leadership style.

​

In December 2025, Dr. Raiser was appointed a Titans Space Career Astronaut Candidate (ASCAN), reflecting his active involvement in the emerging commercial astronaut ecosystem. Alongside this role, he is deeply engaged in analog astronaut missions and EVA simulations, where theory meets reality under operational constraints. These experiences directly inform his perspective on astronaut training, mobility and human-centered system design.

​

His long-standing passion for space exploration is complemented by extensive experience in scuba diving, where operating in hostile environments, managing limited resources and maintaining situational awareness are essential. The parallels between underwater operations and spaceflight training strongly influence his approach to neutral buoyancy training and EVA preparation.

​

As a father of five children, he values responsibility, adaptability and long-term thinking. He is known for being empathetic and supportive, yet direct and clear in communication - fostering strong team spirit while pursuing ambitious, realistic goals. With an entrepreneurial mindset, he recognizes opportunities, drives initiatives forward and remains willing to compromise when it serves the mission.
