Robert Fitzner
I am a mathematician, specialized in probability theory. I am working as applied mathematician and software developer at the Gesamtverband der Deutschen Versicherungswirtschaft (GDV).
Between 2008 and 2019 I was a researcher(post-doc) at different universities in Europe. Most of the time at the University of Technology Eindhoven. I was part of the Network project and was research fellow at the Institute for Complex Molecular Systems.

Next to being a researcher, I managed the website Network Pages, which promotes research related to networks to a broader audience.

Here you can find a recent version of my CV.. Eine deutsche Version meines Lebenslauf gibt es hier . A third version aim at the scientific community is here.


The majority of my research was in the field of statical physics. I refined a perturbative method to prove the so-call mean-field behavior for a number of models.
Further, I worked with groups from the ICMS. In these projects I assisted chemists to understand mechanism that are not directly observable.
More information can be found here.


Part of my work for the consisted of creating visualizations of processes and algorithm on network. Additionally, I implemented tools to simulate/sample the mathematical models during my PhD. The result of this can be found here.
You are welcome to use all images, simulations and demos for your own uncommercial&scientific use.

The network pages

The aim of the is to present research related to networks to broader audience. It explains problems regarding networks, algorithms to analyze networks and mathematical models, that are used to analyze how networks are created and predict properties of large networks.
