Short Bio

Jörg Daubert studied computer science with a focus on IT management until 2011. In 2016, he obtained his Ph.D. with the thesis on "Anonymous Publish/Subscribe Overlays" at Technische Universität in Darmstadt. Since 2014 he is acting as Area Head of the "Secure Smart Infrastructures" group; since 2016 he is joint PostDoc and Area Head of the "Smart Protection in Infrastructures and Networks" (SPIN) group with 9 researchers within the Telecooperation Lab under Prof. Mühlhäuser in Darmstadt. Starting 2016, Jörg Daubert is also coordinating the research training group (doctoral college) "Privacy and Trust for Mobile Users" with 11 Ph.D. student positions.

Jörg Daubert also worked in industrial research for AGT International, a major industry player in Internet of Things and data analytics, from 2011 to 2015 and is freelancing as an IT consultant from 2011 onwards.

Topics for Bachelor and Master Theses

Please have a look at https://www.tk.informatik.tu-darmstadt.de/de/teaching/abschlussarbeiten-d/ for open theses. We often offer a selection of challenging topics in the area of privacy-preserving communication networks. The focus can be either theoretical – developing attack and protection concepts, or practical – analyzing the aforementioned attacks and concepts via simulation. You can write the thesis in English or German.

Abstract <div>The introduction of more and more local and distributed energy resources (DER) into the current centralized electrical grid poses new challenges to energy distribution. DERs are significantly smaller in production capabilities than central power plants and their production is highly fluctuating. This means that their influence on the electrical grid is difficult to plan for, especially in brown-out situations, when there is not enough energy available to supply all consumers. This work focuses on the subproblem of fair electricity distribution in brown-out phases. Currently, network segments are switched on and off in a round-robin manner, regardless if there are local producers in these segments or not. However, enabling segments that include local producers more often would improve the overall amount of energy available during the brown-out phases, and thus, this measure would increase the number of supplied consumers. We propose new algorithms that leverage the power of local producers, but still keep a fair energy distribution for all consumers. Therefore, we evolve the current notion of fairness to improve the overall quality of service by taking into account equal supply times as well as maximizing the number of supplied consumers. The proposed algorithms are compared to the current state of the art approach in the German electrical grid. Therefore, extensive simulations based on real-world lowvoltage residential area networks were conducted. The results indicate an improved quality of service during brown-out phases. Moreover, the proposed method is not limited to low-voltage residential areas, but also applies to all hierarchy levels of the energy grid, ranging from the distribution grid down to future households implementing smart grid technologies.</div>

Bachelor Thesis

in progress

Mittlerweile gibt es ein zahlreiches Angebot an OSN-Anbieter, welche sich in verschiedensten Branchen mit teilweise sich unterscheidenden Zielgruppen befassen. Wer sich schon mal damit befasst hat, stellt schnell fest, dass die meisten Anbieter ihre Dienstleistung kostenfrei oder zumindest den Großteil ihrer Dienstleistung kostenfrei anbieten. Wie also funktioniert dieses Geschäftsmodell? Warum fahren Unternehmen wie Google, Facebook, Twitter und etliche Andere jährliche Gewinne in Milliardenhöhe ein, obwohl die Nutzung ihres Dienstes (Soziales Netzwerk) ganz offensichtlich kostenlos erscheint?
