  • Research
    My research interests lie in the field of particle physics, cosmology and  astrophysics. The topics of my research are the investigation of mechanisms that underlie the evolution of the Universe,  from very early stages up to the formation of contemporary macroscopic structures and individual  astrophysical objects, precision testing of the basic forces of nature using data analysis from high energy astrophysics observations,  gravitational waves astronomy and large hadron collider (LHC). Also, I have a strong interest in contributing into the building,  commissioning and performance monitoring of modern high energy physics detector systems.
