I work on experimental light–matter interactions with trapped ions, with a focus on quantum state engineering, photon correlations, and collective light-matter dynamics of trapped ions crystals.

Education
I am a PhD researcher in the Department of Optics at Palacký University Olomouc, working experimentally with trapped calcium ions. My research involves laser cooling and coherent control of the internal and motional states of ions, including the preparation and characterization of non-classical motional states.
I primarily focus on studying the optical emission from trapped-ion chains through photon-correlation and interference measurements, exploring collective effects such as bunching, antibunching and coherent optical interference. I am also interested in developing experimental techniques for improved motional control, including sideband and EIT cooling, and in understanding how these controlled atomic systems can be used to investigate quantum optical phenomena.
