Prof Paul Roach
PhD, BSc, PGCEd/Dev, MIMA CMath
Career Summary, Specialist Projects and Academic Activities:
I completed a PhD in computer science (Fourier Methods for Curve and Surface Smoothing in Computer Aided Design) at Cardiff University in 1990, where I stayed until 1993 as a Research Fellow in the department of Computer Science. I then took a position as a Designer and Systems Administrator at Interface 4 Ltd, Cardiff, working on educational training programmes and consultancy for the International Labour Organization, before taking up my current post at the University in 1994.
I have held roles as a researcher, research supervisor, year tutor, and undergraduate degree award leader, and am currently the Head of Postgraduate Research Studies. In my time at the University of South Wales I have successfully supervised 8 research students to the award of PhD and MPhil, and currently supervise another 7 research students.
Currently, I am the grant holder for two Engineering and Physical Sciences Research Council CASE awards. The first is with Newport-based company GXS, to automate the generation of product data quality rules in the Retail Fast Moving Consumer Goods and Consumer Electronics sectors. The second is with OSTC (Wales) in Swansea, to design of a decision support system that employs trading algorithms to advise on buy/sell prices using market indicators and trading rules. I am the grant holder for an HPC Wales Fujitsu Research Studentship in the modelling of financial asset behaviour. I am also involved in a further CASE award and a European Commission Research Fund for Coal and Steel project with TATA Steel, in extending knowledge in the mathematical modelling of the dynamics of the heating processes within industrial reheating furnaces.
I play an active role in marketing and recruitment duties.
