Graph machine learning (Graph ML) is an emerging field of artificial intelligence (AI) motivated by the ubiquity of graph-structured data in real-world applications. Graph neural networks (GNNs) serve as a key technology in this area and are successfully used in recommendation systems, financial crime analysis, cybersecurity, and social and biological network analysis. However, conventional GNN architectures are limited in the type and complexity of graph patterns they can detect. For example, cycles, cliques, and frequent motifs can serve as highly discriminative signatures when analysing financial, biological, and social networks. However, cost-efficient and scalable discovery of such patterns in large graphs using neural-network-based approaches is challenging. Although these patterns can be detected using purely combinatorial approaches, such approaches lack statistical learning and adaptation capabilities and have high computational complexity.
A key objective of this project is to identify the trade-offs between combinatorial and neural-network-based approaches in the Graph ML space. We aim to combine and unify combinatorial algorithms and GNNs based on linear-algebra-based primitives, and achieve more efficient and scalable solutions. Our goal is to answer questions like the following:
The project will cover some real-world applications of Graph ML in the financial space, including analysis of financial transaction networks to detect criminal activities such as money laundering and fraud. In this area, we will explore new ways of combining GNNs and Large Language Models (LLMs) to construct machine learning solutions that can operate on graph-structured data with rich sets of node and edge features.
We are looking for a candidate who satisfies the following requirements:
Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.
Fixed-term contract: 4 years.
Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.
Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2872 per month in the first year to € 3670 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School.

Challenge. Change. Impact!
The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment – which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.
