The group of Ali Abbasi is offering multiple positions for Ph.D. candidates interested in the area of embedded systems security. Our group's main aim is to design defense mechanisms and break existing embedded systems to improve their security. We combine deep technical insights of both firmware and hardware to build novel analysis techniques, allowing us to tackle hard-to-test and previously unknown attack surfaces. We also design and implement new methods to protect embedded systems against various classes of attacks, both on the hardware and firmware level.
For hardware security-oriented Ph.D. positions, we are looking for candidates with a strong interest in:
Hardware-assisted security testing and hardware vulnerabilities
Side-channel attacks (e.g., power analysis and instruction-level side channel profiling)
FPGA programming and system building at the board-level around customized circuits
RISC-V and ideally one of its open source designs
Computer architecture design, simulation, and performance evaluation
For software security-oriented Ph.D. positions, we are looking for candidates with solid programming skills in low-level languages like C/C++/Rust/Assembly and in-depth knowledge of operating systems. The candidate should also be interested in at least one of the following topics:
Firmware reverse engineering and/or exploit development
Automated software testing (e.g., fuzzing), especially with an interest in hardware/software-assisted firmware testing
Space assets security (e.g., in-orbit satellite systems security)
Security of Industrial Control Systems (ICS), Electronic Control Units (ECUs), or mobile basebands
For both types of positions, actively playing CTFs, having a public track record of vulnerability research, or building open-source security analysis tooling is a plus. A person with an offensive security mindset will enjoy the work in our group.
The group of Sebastian Brandt is looking for PhD Candidates and Postdocs interested in working in the theory of distributed and parallel algorithms. Possible topics include distributed complexity theory, algorithms for symmetry-breaking and other fundamental graph problems, distributed lower bounds, the role of randomness in distributed computing, and many others. Besides computer scientists, we expressly encourage bright students from maths (in particular pure maths) to apply if they are interested in algorithmic questions.

The group of Krikamol Muandet has multiple openings for Ph.D. students with a strong interest in the broad areas of machine learning (ML). The group's research aims at understanding the principles that enable autonomous agents to learn from past experience and interact succesfully with complex environments, and to use this understanding to design new learning algorithms. The research theme spans the following areas:
Prediction: How do we design ML algorithms that can cope with distrbutional shifts? The topics of interest are domain adaption (DA), domain generalization (DG), out-of-distribution (OOD) generalization, and robustness. Kernel methods, kernel mean embedding of distributions and applications thereof are our mathematical arsenal to tackle these problems.
Causation: How do we leverage cause-effect relationships in improving ML models, and conversely how do we use sophisticated ML methods to aid causal inference in complex environments? Topics of interest are unobserved confounders in causal inference, spurious correlation in machine learning, distributional treatment effects, counterfactual inference, and algorithmic decision making. Natural experiments and quasi-experimental designs such as instrumental variable (IV), proxy variables, and regression discontinuity design (RDD) offers tools to address these problems.
Regulation: How do we regulate the deployment of ML models in heterogeneous environments to ensure the democratic use of AI? Topics of interest are feedback loops and strategic behavior. To gain a better understanding of these problems, we will be adopting techniques from algorithmic game theory, mechanism design, social choice theory, and other related sub-fields of economics.
Successful candidates are expected to have an excellent master's degree in Computer Science, Mathematics, Statistics, or a related discipline. A prior research experience and proficiency with programming languages are a plus.
The group of Mridula Singh is looking for a PhD candidate with a strong research interest in wireless systems security. The group's research focuses on enabling secure communication, positioning, and combining sensor modalities for autonomous systems. The technologies of interest are CANBus, UWB, WiFi, 5G, LEO, and GNSS. Example research topics will include:• Exploring security vulnerabilities of the communication technologies mainly at the physical and logical layer
• Secure sensor fusion
• Designing secure positioning architecture for 5G
• Secure time synchronization
• Location privacy
Students with a strong interest in 5G's physical and logical layer will be given preference. It will be a plus if the student is interested in using software-defined radios like USRPs and open-source RANs for LTE/5G. The student should have taken some introductory courses on digital circuits and wireless systems or be strongly inclined towards this field.
The group of Sebastian Stich is looking for a PhD candidate with a strong research interest in the analysis and development of optimization strategies for training machine learning models. The group's research focuses on distributed algorithms (such as federated and decentralized learning), algorithms for differentially private, robust, and fair machine learning, and on distributed artificial intelligence (see also www.sstich.ch for past and current research). It will be a plus if the student is motivated to work on theoretical challenges that arise in practical application in the fields of biology and health (e.g., structured, or multimodal data, low sample sizes, etc.). Within this project, the student will have the opportunity to collaborate with partners within the Helmholtz AI unit.
Requirements: The candidate is expected to have an excellent degree at the MSc level in mathematics, statistics, computer science or a related discipline. A solid mathematical foundation (e.g. probability theory, statistics, calculus, and linear algebra) is a must, experience in optimization, machine learning, data science or with a ML framework such as e.g. PyTorch, is a plus.
The group of Andreas Zeller is looking for Ph.D. candidates and Postdocs with research interests in program analysis, software testing, and automated debugging.
