Scientific activities

Current scientific interests

       Titanium alloys are the principal field of my research activites. Study in the physics of titanium alloys involves investigation of microstructure, thermomechanic treatment, phase transformation, mechanical properties and also applications of titanium alloys. Young research team is currently working in this field at Department of Physics of Materials. We are proud on our current cooperation with other Departments at Faculty of Mathematics and Physics; with several institutes of Czech Academy of Sciences; top foreign research teams (USA, Germany, Russia) and also Czech company Beznoska Ltd. dealing in body implants.

    In this field, I offer bachelors and diploma thesis. Master students are expected to present their results at international conferences and continuation on doctoral program is recommended.

    Our team also welcomes any international cooperation considering titanium alloys and their applications.
