## Professional career

Can be roughly divided into three different parts:
### Years 1973 - 1981

PhD in mathematics in 1973, University of Helsinki.
Theoretical studies and research in Fuctional Analysis,
University of Helsinki and Helsinki University of Technology.

Student of professor *Klaus Vala* who started a seminar
in functional analysis at the University of Helsinki in 1970.
I continued running the seminar, initially together with Klaus Vala
and later with some other colleagues and/or students of mine.

The seminar is still active,
as you can see.
