Jakub received his PhD in 2011 at Charles University (Prague, Czech Rep.) where he worked on the statistical studies of gamma-ray bursts (GRBs). Then he became a postdoctoral researcher in the Ewha Womans University (Seoul, Korea) and in the Sungkyunkwan University (Suwon, Korea) where he mainly worked on preparation of the UFFO-Pathfinder GRB instrument which was launched on the Lomonosov satellite. Then he moved to the National Taiwan University (Taipei, Taiwan) where he worked on testing the isotropy of the Universe using GRBs. There he also worked on the Taiwan Astroparticle Radiowave Observatory for Geo-synchrotron Emissions (TAROGE) for the detection of ultra-high energy cosmic rays (UHECR) and on the ANtarctic Impulsive Transient Antenna (ANITA) which was a long-duration balloon experiment to detect ultrahigh-energy neutrinos (UHEN). Next he moved back to the Czech Republic to the Charles University for a postdoctoral position.

He is now working at the Department of Theoretical Physics and Astrophysics at Masaryk University and in the Eötvös Loránd University (Budapest, Hungary) where he continues his research on GRBs and works on the development of CubeSats capable of detection and localization of GRBs. These projects are HERMES, CAMELOT, GRBAlpha and the GRB instrument on board of the VZLUSAT-2. His fields of expertize are GRBs, instrumentation for their detection and statistical methods for data analysis.
