dr. R. Holz (Ralph)

I am a Full Professor at the University of Münster, and I also work part-time in the Design and Analysis of Communication Systems Group at the University of Twente.

Until 2019, I was a Lecturer in Networks and Security at the University of Sydney (that’s Asst. Prof. in other systems), Australia. Before that, I was a Researcher at NICTA (later CSIRO's Data61), also in Sydney, where I worked on network security and was part of the Security Business Team.

I hold a PhD from Technical University of Munich. I did both my post-grad and under-grad studies at Eberhard Karls University, Tuebingen, one of Germany’s classic universities.

Organisaties

My research interests revolve around understanding and improving the Internet for everyone, with a particular focus on security aspects. Most recently, I have been working on

• Global-scale measurement of Internet service deployments and their security
• Data-driven security mechanisms
• Analysis of emerging technology and its implications

I view my work through the lens of real-world implications. The tech is not always what matters—it’s the embedding in our world that makes it meaningful. Hence, I work with other disciplines and industry alike to make the Internet a safer, more secure, and altogether more interesting and useful place.
