Cross-disciplinary research and projects

Professor Phil Brown’s research projects;

  • Pfizer case award
    Funded By:    Pfizer
    Period:           2001 – 2004
  • Pfizer Consultancy Analysing Mass Spectroscopy Proteomic Data
    Funded By:    Pfizer
    Period:           2007 – 2009

    Funded By:    NIH (USA – National Institutes of Health)
    Period:           2007
    Collaboration between Professor Phil Brown, University of Kent and Dr Jeffrey Morris, MD Anderson Cancer Center, Houston, USA.

The Stochastic models of yeast prions project was a collaboration of staff across the Faculty of Sciences;

  • Professor Mick Tuite (Biosciences)
  • Professor Martin Ridout (Maths and Statistics)
  • Professor Byron Morgan (Maths and Statistics)
  • Dr Lee Byrne (Biosciences)
  • Dr Diana Cole (Maths and Statistics)

Funded By:   Biotechnology and Biological Sciences Research Council (96/E18382)
Period:           2004 – 2007
The aim of the work is to use stochastic modelling techniques to improve our understanding of prion proteins in the yeast Saccharomyces cerevisiae.
The BBSRC end-of-grant review awarded this project an A grade – “Very high-class work that has produced results of considerable scientific importance in a cost-effective way and met almost all of the agreed or related key objectives”.
