Scientific experience includes over 30 years of work in the PTŚ UMCS technology team. The main scientific interests concern the technology of producing silica glass and high silica glasses by the MCVD and FCVD methods as well as the assembly method used for the production of preforms for microstructural optical fibers. In addition to research issues, my duties include constant supervision over MCVD and FCVD technological lines and their modification for the production of preforms for optical fibers with shaped properties.
