Trosolwyg
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.

Ymchwil
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.

Bywgraffiad
Mae fy PhD mewn Prosesau Stochastig, a dechreuais ymddiddori mewn Epidemioleg a Gofal Iechyd yn gyntaf wrth ymchwilio i ddileu brech y frech wen ar draws y byd ddiwedd y 1960au a dechrau'r 1970au.
Ers hynny, rwyf wedi ymgymryd â nifer fawr o ymgynghoriaethau a chontractau gyda sefydliadau'r llywodraeth a chydag amrywiaeth o gwmnïau cyhoeddus a phreifat, gan gynnwys:
- GlaxoWellcome (GlaxoSmithKline)
- Ysbyty Athrofaol Cymru
- Y Gwasanaeth Iechyd Gwladol
- Llywodraeth Cynulliad Cymru.
Rwyf hefyd wedi gweithio'n helaeth ym maes trafnidiaeth, gan gyfeirio'n benodol at broblemau tagfeydd, ac rwyf wedi cynnal ymgynghoriaethau gyda BP Oil Ltd, Adran Drafnidiaeth, British Steel, Welsh Office, Maunsell Consultancy Services, Awdurdod Camlas Suez, Transport Research Laboratory, ac ati.
Rwyf wedi gweithio mewn sawl rhan o'r byd gan gynnwys Ewrop, UDA, Canada, Affrica, y Dwyrain Canol, y Dwyrain Pell, Awstralia a Seland Newydd.
