Professor Jeff Griffiths

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.
