Timo Sajavaara

Timo Sajavaara is a Professor at the Department of Physics, University of Jyväskylä, affiliated with the Faculty of Mathematics and Science. He leads the Accelerator Laboratory (JYFL-ACCLAB) and co-directs the Nanoscience Center (NSC). He obtained his docent title in Experimental Materials Physics in 2006 at the same institution. His research employs accelerator-based methods to investigate material properties at atomic scales, with applications spanning fundamental science and industrial R&D.

His research focuses on:

• Ion beam modification of nanostructures
• Atomic layer deposition (ALD) for thin films
• Nanomaterial characterization techniques
• Energy-related materials including batteries and catalysts
• Radiation effects on embedded nanoparticles

Recent publications (2019-2022) demonstrate consistent work in nanomaterial fabrication, surface engineering, and ion beam technologies. Key trends include atomic-scale material modification (67% of publications), energy applications (40%), and novel characterization methods (33%).

He leads multiple EU/national projects including:

• RADIATE (EU, 2019-2023): Ion beam technology advancement
• Novel nanostructure morphologies (Research Council of Finland, 2017-2021)
• RECYCLABLE MATERIALS DEVELOPMENT (EU, 2022-2026)
• gH2ADDVA (Regional Council, 2024-2026): Green hydrogen technologies

He collaborates with the JYFL Accelerator Laboratory and Nanoscience Center, focusing on instrumentation development for materials research.
