on Monday 26th of May at 11:00 I will defend my PhD.
The defense will take place in room 003 in the IWI building,
Engehaldenstrasse 8, 3012 Bern.
After the defense, there will be an apero in the Cafeteria of the
building S14 (Schuetzenmattstrasse 14).
Everybody is invited to the defense and to the apero.

TITLE: Sub-method Structural and Behavioral Reflection
Computational reflection is a fundamental mechanism in object oriented
Reflection has proved useful in many contexts, such as in the design
of development environments,
language extension, and the dynamic, unanticipated adaptation of
We identify three problems with the current approach to reflection in
object oriented languages:
partial behavioral reflection needs to be anticipated, structural
reflection is limited to
the granularity of a method, and behavioral reflection cannot be
applied to the whole system.
To address these problems, we extend structural reflection to cover
and present how sub-method structural reflection supports
unanticipated partial behavioral reflection.
We add the concept of context to represent meta-level execution and
show how this
allows behavioral reflection to be applied even to system classes.
We describe an implementation in Smalltalk. Benchmarks validate the
practicability of our approach.
In addition, we present an experimental evaluation in which we show
how the system is used for dynamic
analysis. We realize dynamic feature analysis by annotating the sub-
method structure of the system
directly to denote features instead of recording full execution traces.
