Dr. Jaroslav Kováčik is a senior researcher at the Institute of Materials and Machine Mechanics, Slovak Academy of Sciences, Bratislava (Slovakia). He is involved in the investigation of metallic foams, i.e., the measurement and modelling of mechanical and physical properties. His work is devoted to metal matrix composites, focused on the physical and mechanical properties of copper–graphite materials. He also deals with the use of concentrated solar power for the powder metallurgical preparation of Ti and Ti composites and the solar nitridation of Ti.
