Software Security

Marcel Bƶhme is a tenure-track faculty at MPI-SP and head of the Software Security research group. His current research interest is the automatic discovery of software bugs and security flaws at the very large scale. One part of his group develops the foundations of automatic software testing (an approach to finding bugs by auto-generating executions) to elucidate fundamental limitations of existing techniques, and to explore the assurances that software testing provides when no bugs are found. The other part of his group develops practical vulnerability discovery tools that are publicly available and widely used in software security practice. Read more

Safety- and Efficiency- Aligned Learning

Jonas Geiping leads a joint research group at the Max Planck Institute for Intelligent Systems and the ELLIS Institute TĆ¼bingen. His group is interested in questions of safety and efficiency in modern machine learning. There are a number of fundamental machine learning questions that come up in these topics that we still do not understand well. In safety, examples are questions about the principles of data poisoning, the subtleties of water-marking for generative models, privacy questions in federated learning, or adversarial attacks against large language models. Can we ever make these models ā€œsafeā€, and how do we define this? Are there feasible technical solutions that reduce harm? Further, the research group is interested in questions about the efficiency of modern AI systems, especially for large language models. How efficient can we make these systems, can we train strong models with little compute? Can we extend the capabilities of language models with recursive computation? How do efficiency modifications impact the safety of these models? Read more

Social Computing

Krishna Gummadi heads the Social Computing research group at the Max Planck Institute for Software Systems. He is broadly interested in understanding and building networked and distributed computer systems. Currently, the group's research focuses on social computing systems: an emerging class of societal-scale human-computer systems that facilitate interactions and knowledge exchange between individuals, organizations, and governments in our society. A few examples include social networking sites like Facebook, blogging and microblogging sites like LiveJournal and Twitter, and content sharing sites like YouTube, among many others. Through user studies, examining data, and building systems, the group aims to understand, predict, and control the behavior of their constituent human users and computer systems. Read more
