**Professor Paul Busch **(paul.busch@york.ac.uk)

Professor (Department of Mathematics)

I am a mathematical physicist with extensive research experience in conceptual and mathematical foundations of quantum physics. Current research interests include the quantum-classical contrast, quantum limitations of measurements and measurement uncertainty relations, with implications for quantum information processing and metrology, and issues between quantum theory and relativity. I have co-authored two monographs, "The Quantum Theory of Measurement" (with P. Lahti and P. Mittelstaedt), and "Operational Quantum Physics" (with M. Grabowski and P. Lahti).

**Professor Edwin Hancock** (edwin.hancock@york.ac.uk)

Professor (Department of Computer Science)

My original research background is in high energy nuclear physics, but I have been working in Computer Science for the past 30 years. My current research interests are in structural pattern recognition, machine learning, complex networks and computer vision. One of the themes running through this research is developing mathematical algorithms for the analysis of network structures. In machine learning and complex networks, algorithms based on random walks on graphs have proved to be extremely powerful for detecting large-scale structures within networks and for developing compact characterisations of networks. Over the past 10 or so years, I have become interested in a number of topics in network science that are rooted in physics. These include the study of quantum walks on networks, and the statistical physics of network evolution.

Professor (Department of Computer Science)

I am the Director of the York Centre for Complex Systems Analysis (YCCSA), a community of researchers drawn from different departments developing novel mathematical, computational and analytical methods and tools for the analysis and modelling of complex systems. My research interests include unconventional computation and non-von Neumann architectures.

**Dr Stefan Weigert** (stefan.weigert@york.ac.uk)

Reader (Department of Mathematics)

I am interested in non-relativistic quantum mechanics, especially in the foundations of quantum mechanics and quantum information. In recent years, I have mainly worked in the following areas:

- uncertainty relations

- mutually unbiased bases

- quantum state reconstruction

Earlier on, I have contributed to quantum state reconstruction for spin systems and to quantum chaos, more specifically to the question of defining integrability for quantum systems; I also studied the properties of PT-symmetric quantum systems.

**Professor Richard Wilson** (richard.wilson@york.ac.uk)

Professor (Department of Computer Science)

My research interests are wide-reaching but mainly involve the areas of computer vision and pattern recognition, particularly problems involving graphs and networks. I have worked on Bayesian methods for graph matching and the development of spectral techniques for structural pattern recognition, developing new feature sets for describing graphs and networks. I have also published research in the fields of quantum computing, shape-from-shading, speech recognition and protein matching.

My current interests involve trying to obtain a better quantitive understanding of complex networks. I am working on ways to measure the complexity of directed and undirected networks, and how to characterise large networks in an efficient way using walks and cycles. I am also interesting in statistical models of network classes which can be learnt from data.
