Trosolwg

I have been a  member of staff at Cardiff University since 1964 and was Head  of the School of Mathematics for most of the period from 1983 to 2006. I was  appointed Dean of the Science Faculty in 1991.

I have received grants and awards  totaling over £1M. I have been an invited speaker at a large number of  conferences both in the UK and overseas, and have organised several  international conferences. I am the author of over 100 publications and  reports. I have also appeared in expert capacity in several television and radio programmes,  and as an expert witness in High Court actions.

Bywgraffiad

My PhD is  in Stochastic Processes, and I first became interested in Epidemiology and  Healthcare when investigating the world-wide eradication of smallpox in the  late 1960s and early 1970s.

Since that time I have undertaken a large number of  consultancies and contracts with government establishments and with a variety  of public and private companies, including:

  • GlaxoWellcome (GlaxoSmithKline)
  • University Hospital of Wales
  • National Health Service
  • Welsh Assembly  Government.

I have also worked extensively in the field of transport, with  particular reference to congestion problems, and has held consultancies with BP  Oil Ltd, Department of Transport, British Steel, Welsh Office, Maunsell  Consultancy Services, Suez Canal Authority, Transport Research Laboratory, etc.

I've worked in many parts of the world including Europe, USA, Canada, Africa,  Middle East, Far East, Australia, and New Zealand.

I have been  awarded a number of Research Council grants, and have received financial support  from the European Union and World Health Organisation for my work on modelling  the spread of HIV/AIDS.

From 1987 - 1997 I was UK representative on the EU  Concerted Action to investigate the control and spread of HIV/AIDS in Europe.  This project involved about 70 researchers, with representatives from all EU  countries, plus invited guests from USA.

I have lectured widely on HIV/AIDS,  particularly in USA, and was the lead speaker at the Baltic Operational  Research Conference held in Vilnius, Lithuania in 2003.

In 2008 I was awarded an  EPSRC Science and Innovation grant (LANCS Initiative) in conjunction with the Universities of Lancaster, Nottingham, and  Southampton.  Cardiff's share of this grant  was approximately £1.3 million.

I lead the Healthcare Research  Cluster of the LANCS Initiative. Current and recent projects include:

  • Investigation of risk factors associated with diabetes mellitis
  • Study of treatment effects for HIV/AIDS
  • Macro-vascular disease in diabetes patients
  • Age effects in patients with HIV/AIDS
  • Intensive Care and High Dependency facilities in a large Teaching Hospital
  • Comparison of treatments for osteoporosis
  • Methicillin Resistant Staphylococcus Aureus and Methicillin Sensitive  Staphylococcus Aureus mortality comparisons
  • Diagnosis of bone mineral density disease
  • Modelling waiting times and waiting lists in National Health Service hospitals  in Wales
  • Modelling  treatments regimes in a rehabilitation hospital
  • Modelling  hip-fracture facilities in a teaching hospital.

Research interests

  • Queueing Theory
  • Discrete Event Simulation
  • Healthcare Modelling
  • Epidemiology
  • Transport Modelling
