Jef Laga
Mr Jef Laga
Number theory
Mr Laga is a pure mathematician working in number theory, a field that goes back to the ancient Greeks and Babylonians and aims to understand properties of the whole numbers, the basic building blocks of mathematics. More specifically, he works in arithmetic statistics, which studies number-theoretic objects (like prime numbers or polynomial equations) in families.

He completed an undergraduate degree at Ghent University (with an exchange semester in Paris) and a Master's degree (Part III) at Cambridge. In his PhD thesis at Cambridge, he showed how Lie theory (which is also used in theoretical physics) can be fruitfully applied to study the arithmetic statistics of Diophantine equations.

While at St John’s Mr Laga will continue investigating number theory through the lens of Lie theory, as well as exploring interactions with neighbouring fields such as algebraic geometry, symplectic geometry and singularity theory.

Professor Nic Lane
University Senior Lecturer
Computer Science
Professor Lane studies the design, architecture and algorithms of scalable and robust end-to-end machine learning (ML) systems. His research interests drive towards the development of new forms of ML systems that are revolutionary in how they leverage multi-modal data (e.g. speech, vision, location, inertial information) to infer and reason over complex real-world situations — while simultaneously, maintaining extreme levels of systems flexibility (e.g. distributed execution, adaptation) and efficiency (e.g. compute, memory).

A Luppi
Dr Andrea Luppi
Natural Science (Biological)
General anaesthesia is one of the greatest breakthroughs in the history of medicine, enabling millions of life-saving surgeries each year worldwide. However, we still do not know how anaesthetics influence the delicate functioning of the brain to suppress consciousness. Dr Luppi's doctoral work used anaesthesia as a lens to interrogate brain function to understand how brain architecture orchestrates information processing.

After transitioning from Philosophy to Neuroscience, his PhD combined network science and information theory. He discovered that the interactions between different brain regions are synergistic, carrying more information than the sum of their individual contributions. This neural synergy is diminished when consciousness is lost, whether due to anaesthesia or brain injury. It is also especially prominent in evolutionarily recent regions of the human brain, and greater in humans than in non-human primates.

These discoveries converge on a role of synergy in supporting human cognition, raising the intriguing prospect of using synergy as a guiding principle to develop more human-like artificial intelligence. This is the research that Dr Luppi will conduct during his time as a Fellow of St John’s. He will investigate the role of synergy in supporting cognitive function and dysfunction, both in the human brain and in artificial neural networks.
