Finnish Computer Scientists - Ordered by Citations

NB! If you have just stumbled into this page by accident (e.g., looking up your name from Google) and wonder what is this page about, please check this page one level upwards that has explanations and some additional information

Disclaimer: All information has been gathered from public sources. If you want to add or delete some information about you, please email me. I do this all from my free time. But I welcome information that will help me in updating this page.

Disclaimer 2. Do not take those numbers too seriously without actually studying how Google collects the citations. Moreover, bear in mind that citations differ significantly in subfields of computer science, with practical areas getting a bulk of the citations. Also, for some of the authors, a majority of citations comes from authored textbooks, or even worse, from self-citations. Thus, be careful.

Last update: July ~1, 2010.

All links are clickable. For example, you can sort people according to Cites, Recent (2005+), H-Index, compare institutions to each other, or see people only from a certain institution.

News (20.07.09): people with less than 0 citations are not displayed (this can adjusted with url suffix "&cutoff=xxx").
