  • 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.

    Tapio Nummi obtained his M.Sc.(1986), Lic.Phil. (1990) and Ph.D. (1995) at the University of Tampere. He has been an acting assistant (1985–1986) and a teacher (1987). In 1988 he was an acting research assistant at the Academy of Finland. During 1989 and 1990 he was a researcher at the University of Tampere. He was a researcher at the Academy of Finland during the years 1991–1993. In 1993 he was nominated as a senior assistant for the next five year period. In 1997–1998 he was a researcher at the Academy of Finland. During the academic year 1998–1999 he is an acting Professor of Statistics.
