Teemu Roos

Teemu Roos is a Professor at the Department of Computer Science, University of Helsinki, and a Principal Investigator for the Complex Systems Computation Group under the Helsinki Institute for Information Technology. He serves as a Supervisor for the Doctoral Programme in Computer Science and leads multiple research initiatives, including Distributed AI in Supercomputing, AI & Kids, and Generation AI. Dr. Roos also holds a Docent title in Computer Science.

His research spans Artificial Intelligence, Machine Learning, and Data Science, with a focus on AI education, graph neural networks, Bayesian modeling, and health informatics. He has pioneered tools like Elements of AI, a free online course now translated into 22 EU languages, and explores the ethical implications of AI-generated content in authorship and inventorship.

The 15 most recent publications highlight applications in environmental forecasting (e.g., Mediterranean Sea via graph-based deep learning), healthcare (e.g., skin cancer detection with transfer learning), and social media analysis (e.g., explainable AI platforms for K-12 education). Methodologically, his work advances clustering algorithms, dimensionality reduction, and approximate nearest neighbor search.
