1 January - 19 June 1997

**Organisers**: M.Broue (*Paris*), R.W. Carter (*Warwick*), J Saxl (*Cambridge*)

The main theme of the workshop is to survey the wide variety of methods currently being developed to study the representation theory of groups of Lie type and related structures in non-defining characteristic.
