curriculum vitae

Dr.-Ing. habil. Nikolai Kashaev concluded his studies in Energy-Related Mechanical Engineering with the advanced subject of electrical aerospace engines and power plants at the Bauman University of Technology in Moscow in 2001.

Subsequently, he worked as a scientific employee at the Foundation Institute for Materials Technology in Bremen for four years. In 2005, he obtained his doctoral degree in Materials Engineering. After various activities in industry, he has been the head of the Laser Processing and Structural Assessment department at the Institut of Materials Mechanics at the Helmholtz Centre Hereon in Geesthacht since 2010.

In 2018, he qualified to lecture in Materials Engineering (German Habilitation) at the Hamburg University of Technology with the thesis “Laser welding and processing of aluminium and titanium alloys for aerospace applications”. His research interests are laser welding and processing of lightweight metallic materials, residual stress engineering, laser shock peening, damage tolerance assessment, fatigue life prediction of welded and additive manufactured components and structures.
