Research Area:

Tobias' current research area is in the domain of temporal graph neural networks and time series analysis. Here, he is especially interested in applying these for the task of fake news detection in social media networks as well as computer network analysis. Further, he is interested in Large Language models and their application in various domains.

Before starting his doctorate, he worked for one year as a software developer. He received his master's degree in mathematics from the Technical University of Munich and his bachelor's degree in mathematics with a minor in computer science from the Ludwig-Maximilians-Universität. During his studies he worked in research departments at Infineon Technologies AG and Allianz Global Investors GmbH for about 3 years.

Seminar/Bachelor/Master Thesis Topics:

Temporal Graph Neural Networks: Computer Networks can be modeled as a graph that changes over time. The nodes are the PCs, servers, access points, … and the edges are connections/traffic between them. Graph Neural Networks can be used to detect anomalies in the network. The goal of this work is to classify existing approaches to detect attacks in computer networks and implement one aproach and evaluate its performance.

Machine Learning for Port Scan Detection: This thesis will explore the initiation of cyber attacks through open port scans. Detecting such port scans early and implementing timely countermeasures can significantly aid in defense against attacks. Recently, several machine learning-based methods have been developed to identify these port scans. Your task in this thesis will be to conduct a literature review of the relevant papers and compare them with earlier, rule-based approaches.
