Abstract: 
  The inflaton field range is directly related to the amount 
of inflation and the tensor/scalar ratio a given model predicts.  
In scenarios where the inflaton field has a more fundamental origin, 
there are often underlying constraints on the field range which can 
guide our expectations for the type of predictions the fundamental theory 
can reasonably make.  In this talk, I will use the example of brane 
inflation to explore the relationship between the moduli space of 
the canonical inflaton and that of the underlying scalar field.  
I will discuss the observational implications of extending the field 
range using wrapped branes.
