Who's Who

Prof Martyn GuestProfessor Martyn F. Guest

Professor Martyn F. Guest is Director of Advanced Research Computing at Cardiff University. He obtained his B.Sc. in Chemistry from Sussex University in 1967 and his Ph.D. in Theoretical Chemistry, also from Sussex, in 1971 under the direction of Prof. J.N. Murrell.  Following a postdoctoral position with Prof. I.H. Hillier at the University of Manchester, Professor Guest joined the Science and Engineering Research Council in 1972, first at the Atlas Computer Laboratory (Chilton, Oxfordshire), and from 1979 at the Daresbury Laboratory near Warrington. He spent three years as Senior Chief Scientist and Technical Group Leader of the High Performance Computational Chemistry Group at the Pacific Northwest National Laboratory (Richland, Washington, USA). Professor Guest returned to the UK in 1995 as Associate Director of the Computational Science and Engineering Department at the STFC Daresbury Laboratory (UK) before taking up his present position at Cardiff University in Mach 2007.

Professor Guest is presently an Honorary Professor in Physics at the University of Edinburgh and an Honorary Reader in Chemistry at the University of Manchester.  His research interests cover a variety of topics in the development and application of computational chemistry methods on high performance computers. Professor Guest is lead author of the GAMESS-UK electronic structure program, and has written or contributed to more than 230 articles in the areas of theoretical and computational chemistry, and high performance computing.


Dr Christine KitchenDr Christine A. Kitchen

Dr Christine Kitchen is the Manager of ARCCA. She obtained her B.Sc in Chemistry from Sheffield University in 1996 and her Ph.D. in Theoretical Chemistry in 2001, also awarded by Sheffield University. Her postgraduate research was performed under the guidance of Prof. B. T. Pickup at Sheffield University and Dr. J.A. Grant at Zeneca (now AstraZeneca) Pharmaceuticals. Following the award of her doctorate, Dr Kitchen spent a further 3 years in the Molecular Modelling and Drug Design group at AstraZeneca (Alderley Park, Cheshire, UK). Here, she undertook research on a grid-based Poisson-Boltzmann model to predict the electrostatic properties of molecules, and acted as the system administrator responsible for a variety of SGI systems and a Linux Cluster.

Dr Kitchen joined the Distributed Computing (DisCo) group, part of the Computational Science and Engineering Department at the STFC Daresbury Laboratory (Warrington, UK) in January 2004. During her time at Daresbury she led the Commercial Outreach and Training activity within the DisCo group where she undertook a variety of roles, from system administrator through to interactions with Universities and Industry, providing technical expertise to assist various sites with mid-range cluster computing.

Dr Kitchen started her current position at Cardiff University in September 2007.


Dr Hugh BeedieDr Hugh Beedie

Dr Hugh Beedie is the Chief Technology Officer (CTO) for Information Services (INSRV) as well as ARCCA.

He has been working in Cardiff University for over 25 years, carrying out a range of technology-related roles in the computing service. He was responsible for developing Cardiff's Local and Wide area networks from the early days of dumb terminals and no Internet, through to the more recent period of Gigabit ethernet networking and a ubiquitous Internet. Along with the development of the underlying network, he has also led the teams responsible for developing many workstation and server-based IT services for the entire campus.

He has been CTO of INSRV and ARCCA since September 2006, and since that time has been working on: the creation of ARCCA and the project for the ARCCA SRIF3-funded tender for HPC equipment, the University IT Programme, and an energy saving programme for all IT services.

His major role as Technical Design Authority in the University IT Programme is to ensure that all University IT services are designed to inter-operate with maximum functionality and minimum complexity, according to well defined IT standards.

His ARCCA responsibilities are to ensure that, although separate from INSRV, ARCCA's services will integrate seamlessly with those of INSRV. He has also played a major role in, and was the original INSRV sponsor of the Condor Compute service.

His energy saving remit is supported by his membership of the University's Energy Management initiative, and is being satisfied by technical workstation and server design changes, investigation and change of the cooling systems used in the University's data centres, and advice on purchasing policies and user education to minimise energy consumption of PCs.


Mr Thomas Green Mr Thomas Green

Thomas Green started at ARCCA as a Senior Programmer in September 2013. He graduated from UMIST (now University of Manchester) with a Masters in Chemical Engineering in 2002. His dissertation helped develop code written in Fortran to simulate granular materials where his interest in research computing began. After some research using C++ to model foams, in 2006 he started working at the Met Office in Exeter and was part of a team responsible for maintaining and developing the Unified Model. Whilst working at the Met Office he gained knowledge of MPI, OpenMP and the use of many libraries and languages used in the scientific field.

His work at ARCCA will focus on helping researchers use its computing facilities more effectively.   He will also use his experience to help foster good working practices within the University and his knowledge will help with training researchers have the required software development skills for future research.

Dr Christopher DicksonDr Christopher Dickson

Dr Chris Dickson co-ordined the Advanced Research Computing (High-End Computing) programme at Cardiff University up to October 2007. In his new role within INSRV, Dr Dickson will still be working on collaborative opportunities between INSRV and ARCCA.

He graduated from the University of Glasgow in 1989, before joining Cardiff University to complete his PhD in 1993. Dr Dickson worked for a commercial IT training firm in Cardiff (1994-96), and managed a high school library and resource centre (1996-97). He then rejoined the University in 1997 as an Information Officer and Computing Advisor for Information Services, before becoming Departmental IT Liaison Officer (2000-2003), and then Liaison and Strategy Officer (2003-2004).

Dr Dickson serves on the University Court and is a member of the University's Social and Community Action Network (SCAN) Committee, which promotes links between staff working in different areas of the University and raises money for the Tenovus cancer charity and local good causes
