With the ongoing works on preparations of High-Luminosity LHC, there is a need to enhance the performance of various experiments on the collider as well. This is also the case of the experiment ATLAS and its subdetectors such as Inner Detector which will be completely replaced by new all-silicon Inner Tracker (ITk). The PhD student will join the ATLAS UPGRADE experiment, and he/she will get familiar with data analysis methods in high energy physics. He/she will contribute to the ITk strip module performance simulation, testing and evaluation procedure, and the module final production.

The second part will involve studies of how high-energy quarks and gluons interact with the quark-gluon plasma (QGP) that is created in heavy-ion collisions at the LHC. Such an extreme state of matter is believed to have existed during the first microseconds after the Big Bang. The student will focus on studies of jets using contemporary substructure techniques as well as exploiting the role of flavour, jet size, and path-length in the medium.
