Dominik is a physicist working in quantum information, quantum metrology, quantum batteries, thermalization of quantum systems, and the concept of entropy. He is known for developing several formulae for the Quantum Fisher Information matrix - a quantity that determines the sensitivity of a quantum detector and thus helps in designing them, and for the development of Observational entropy - generalization of Boltzmann entropy to quantum systems, which shows dynamical thermalization of quantum particles. He is the founder of the Observational entropy appreciation club. He currently serves as a Team Leader at the Institute for Basic Science, South Korea.
His other interests lie in psychology and its effects on society. He is also interested in sociology, economy, and stock markets. He loves sharing and discussing his knowledge with others. In his free time, he enjoys outdoor sports, dancing, playing the piano, and getting lost in the music.
