Dr Marco Valentino

Marco Valentino is a Lecturer in Artificial Intelligence (AI) and Applications of AI in the Natural Language Processing (NLP) group at the University of Sheffield. Prior to joining Sheffield, he was a member of the Neuro-Symbolic AI Group at the Idiap Research Institute and earned his PhD in Computer Science from the University of Manchester.

His research focuses on developing the next generation of AI systems that leverage explanation as a core mechanism for learning and reasoning in complex domains, such as science, mathematics, and healthcare. To achieve this, Marco investigates data-efficient, interpretable, and robust methods for explanation-based AI and NLP models, with a strong emphasis on modular neuro-symbolic integration. Additionally, he develops methodologies to interpret, evaluate, and control Large Language Models (LLMs), focusing specifically on decoupling abstract logical reasoning from language and knowledge acquisition.
