DESCRIPTION:Decomposition numbers encapsulate the relationship between ord
 inary and modular representations of finite groups. Determining decomposit
 ion matrices is a difficult problem\, particularly for the finite groups o
 f Lie type in non-defining characteristic. I will present some recent deve
 lopments which allow us to consider tackling this problem for the quasi-is
 olated blocks of finite groups of Lie type in non-defining characteristic\
 , and discuss some of the strategies and challenges involved in this proje
