Interests

My research interests are broadly in AI & machine learning with a particular focus on relational learning & reasoning, which includes a class of challenging problems that can be naturally characterised on relational structures, such as graphs, knowledge bases, or more general logical representations. The goal is being able to more efficiently and reliably learn from relational patterns and reason over them. This is a highly interactive field, where techniques from knowledge representation (e.g., logical reasoning), machine learning (e.g., deep learning, graph representation learning, probabilistic inference), and theoretical computer science (complexity theory, graph theory) are relevant.
