Since August 2009 I am a professor emeritus of ETH. My last lecture
May, 25, 2009 (Abschiedsvorlesung) is available
here.
A picture taken at this occasion is
here.
Activities:
I am interested and involved in promoting computer science as
mandatory subject in the Gymnasia in Switzerland. Therefore I work
part time in
ABZ, the education center of
Prof. Juraj Hromkovic.
I have chaired a committee of
Informatics Europe
and
ACM Europe
working on a report on Informatics Education
Informatics education. The report
published April 2013 with the title
"Informatics education: Europe cannot afford to miss the boat"
is available
here.
Die deutschschweizerische
Erziehungsdirektorenkonferenz arbeitet an
einer Revision des Schulstoffes:
Lehrplan 21
Unverständlicherweise ist Informatik nicht als Grundlagenfach vorgesehen.
Ich habe dazu einen Artikel geschrieben, der leider nicht publiziert worden ist:
hier ist er.
I am also a guest professor at
Baptist University Hong Kong,
visiting the
Computer Science Department
during Spring Semester from
January to June.
I was a member of the board of
ICTSwitzerland
and also president of its Education Committee
(Kommission Bildung)

Education:
I am interested in CSE education. I was a member of the SIAM Working Group on
Computational Science and Engineering Education and helped to define the
curriculum for that field. I am also one of the fathers of the curriculum for CSE at ETH.
