Jakob Kübarsepp

Jakob Kübarsepp (born 9 February 1947) is an Estonian engineer and materials scientist. He is a professor emeritus and senior researcher at the Tallinn University of Technology (TalTech) and a member of the Estonian Academy of Sciences (elected 2011). In 2024 he received Estonia's national science lifetime achievement award.

Education Kübarsepp studied mechanical engineering at the Tallinn Polytechnical Institute (TPI, now TalTech), graduating in 1970.

Research According to Estonia's Ministry of Education and Research, Kübarsepp's lifetime work includes developing very strong and durable coatings and wear-resistant lightweight composites using powder-metallurgy methods while avoiding certain strategic, expensive, or environmentally hazardous metals (such as tungsten or cobalt). His research has also addressed tool materials and their applications in metal forming, and wear and corrosion processes in powder materials.

In 2005 Kübarsepp led the engineering-sciences award-winning cycle of works on developing micro- and nanotechnological research methods for industrial materials development (state science award).

Awards and honours 1985 – Estonian SSR State Prize (for implementation of research results in production) 2005 – Estonian national science award (engineering sciences; team leader) 2006 – Order of the White Star (4th Class) 2024 – Estonian national science lifetime achievement award

Publications and supervision The Estonian Academy of Sciences has credited Kübarsepp with more than 250 scientific publications and supervision of doctoral research in engineering and materials science.
