 An experimental scientist inclined towards fundamental studies in the field of polymer physics. From the beginning of the adventure with polymer physics in 2000 focused on phase transitions, their kinetics and polymorphism. Currently focused on properties of electrospun polymer fibers, especially, on confinement effects, as well as new approach using polarized light for studying behavior of oriented systems.
