When the Department was founded, the
teaching staff consisted only of a professor and an assistant.
At present there are 9 teaching positions:
two professors, three lecturers, senior assistant, assistant and two full-time teachers.
There are also a number of research staff on fixed-term contracts.
Also a large number of Statistics part-time
teachers have worked in the Department. These include Tomi Seppälä, Anna-Maija
Koivisto,Ismo Lapinleimu, Henri Toukomaa, Merja Jauhiainen, Markopekka Niinimäki, Joni
Lehtinen, Matti Ylén, Jari Parviainen, Pirjo Palmroos, Inka Martti, Lasse Koskinen, Hannu
Oja, Jani-Pekka Virtanen, Minna Åhman and Erkki Mäkelä.

Erkki Liski obtained his M.Sc.(1971), Lic.Phil.(1973) and Ph.D.(1979) at the University
of Tampere. He was an acting assistant and a part-time lecturer in the Department of
Mathematical Sciences from 1969 to 1973. He was an assistant of Statistics in the
Department of Mathematical Sciences from 1974 to 1980 and a senior assistant in 1980. He
was appointed lecturer (1981) and professor in 1996 at the University of Tampere. He has
been a senior research fellow (1983–1986) and senior scientist (1992–1993
and 1998–1999) at the Academy of Finland, a visiting researcher at the Institute
for Advanced Studies in Vienna (1985), and a Humboldt Research Fellow at the University of
Dortmund (1986–1987). He has been an acting Professor in Statistics (1982–1983,
1988–1992 and 1993–1996). He also holds a Docentship at the University
of Jyväskylä (1988–) and at the University of Helsinki (1990–).
Research interests:
- linear models
- regression analysis and multivariate analysis, especially multivariate growth curve
models and data analysis.
