Selected research projects where I have been either Project Manager or in a significant role:

 

  1. European Space Agency (ESA). I served as project manager and technical lead for ACROSS (2011-2012) and FREESTONE (2013-2015), pioneering the first ESA-funded projects studying cognitive radio and spectrum sharing technologies to satellite networks. 
  2. I was a technical manager for the ESA-funded ASCENT project (2018-2020) that implemented licensed shared access (LSA) testbed for satellite-terrestrial systems.
  3. Multiple ESA projects on topics such as development of simulation and emulation testbeds, multi-layer networks and direct satellite-to-device connections.
  4. Multiple large strategic space projects funded by VTT in 2019-2023. Each year the budget around 800 k€. Covering topics such as hyperspectral imaging, constellation design, real-time situational awareness, cybersecurity, direct satellite connections and synthetic aperture radar (SAR) imaging. In addition, couple of smaller projects on autonomous ship technology development.
  5. Multiple projects funded by Tekes/Business Finland. The most notable ones where I have served as  project manager and main researcher include SANTA CLOUDS (2011-2013) on cooperative and cognitive communications and spectrum measurements, 6G_Sat (2021) on developing national roadmap for 6G satellite communications and 6G-SatMTC (2023-2025) that focuses on developing machine-type connectivity and direct satellite connections to critical users. 
  6. Leading the HX research ecosystem activities related to acquisition of next generation  fighters to the Finnish Air Force (2020-2022). The ecosystem included VTT and all main research organizations in Finland + key industrial players. The work led to multiple industrial projects.
  7. Scientific Advisory Board of the Finnish Defence Forces (MATINE) funded project RATIONALE (2009-2012). Adaptive transmission technologies in fading wireless channels and cognitive radio research.
  8. European Defence Fund (EDF) project SPIDER (2023-), space-based intelligence, surveillance and reconnaissance (ISR) development for European needs.
  9. Multiple projects to customers in Finland and internationally (e.g., Netherlands frequency regulation authority,  ESA, Nokia, Polar Orbital, SMEs)
  10. Leading FDF project focusing on disruptive technologies.
