Bruno Klajn was born on February 16, 1987. in Zagreb. After finishing Fifth gymnasium, he enrolled in a research study in physics at the Faculty of Science and Mathematics (PMF) of the University of Zagreb, where he graduated in 2010. PMF. He defended his doctoral dissertation in 2016, after which he was employed as a post-doctoral student at the Physics Department of the Faculty of Medicine. After completing his postdoctoral training, in mid-2022, he moved from the academic environment to the IT sector, where he works as a Data Scientist.

Main areas of scientific research and interest: mathematical physics, high-energy physics, quantum electrodynamics, quantum chromodynamics, single-loop Feynman diagrams, quantum statistics, Gauge theories, aholonomy in quantum physics, quantum Hall effect, development of a platform for quantum computers.

Since 2019, he has been teaching mathematics and statistics courses at ZŠEM as an external lecturer.
