The latest edition of the Stanford–Elsevier database, published on 7 October 2026, identifies highly cited researchers worldwide using standardized citation indicators based on Scopus data. The database covers 20 scientific fields and 174 subfields and provides separate rankings for career-long research impact and citations received during 2025.
In the single-year ranking, Oksanen placed 46th among 18,209 researchers in the Substance Abuse subfield when self-citations were excluded. This places him among approximately the top 0.3% of researchers in that subfield. He was also included in the career-long ranking of the world’s most-cited researchers.
Oksanen’s research spans social psychology, artificial intelligence, digital interaction, online communities, addictions, online harms and technology-related well-being. His interdisciplinary work examines how emerging technologies transform human behaviour, working life and social interaction.
At the Emerging Technologies Lab, Oksanen leads multidisciplinary and international research on the psychological and societal implications of technological change. The latest citation rankings reflect the international visibility and scientific impact of research across these interconnected fields.
The Stanford–Elsevier database uses a composite citation indicator that considers citations, co-authorship and authorship positions. While citation indicators provide information about the reach and influence of scientific publications, they represent only one dimension of research impact.
