Research Interests

Research, consulting and teaching on several areas of management science. Specialist areas include credit scoring and credit control, and use of management science techniques in financial and banking areas. Interests in applications of game theory and logistics, including inventory and replacement.

Work in progress

The main area of research is consumer credit risk and credit scoring and the need to deal with new objectives such as profit scoring. This has led to using survival analysis ideas and Markov chain models in credit scoring and the related areas such as customer relationship management. Aso interested in the problems the internet and customization brings to consumer trading, the impact of the Basel New Accord on retail trading models and the need to develop models of portfolios of customer loans. The second strand of work is the application of Markov decision processes in operations management problems such as inventory, production and repair and replacement. In particular I am looking at the optimal policies for small firms who are more interested in survival than in maximising profit. The third strand is the use of game theory, particularly in search and rendezvous games, cost allocation problems, and learning in games.
