Current Research Interests

UFFO: My research interest is UFFO-pathfinder, which is a space experiment focused on observation of the prompt and early afterglow emission in the uv/optical and gamma-ray range. I am writing a pipeline software for the translation of the telemetry data from this experiment to the FITS files usable by other astronomical data reduction programs. My work also included tests of the gamma detector UBAT of UFFO-pathfinder and testing the on board trigger logic.

GRBs: I am interested in statistical analyses of the properties of the prompt emission of gamma-ray bursts (GRB) such as durations, spectral hardnesses, peak- fluxes, fluences, and spectral lags from the RHESSI, Swift and Fermi satellites. Next interest is a classification of GRBs and their relation to x-ray flashes.

Cosmology: My interest is use of GRBs to study cosmology and the isotropy of the Universe.

Biography:

I come from the Czech Republic where I finished my Ph.D. in the Charles University in Prague, Faculty of Mathematics and Physics, in 2011. Then I went to Korea for a post-doctoral position in Ewha Womans Univesity, Institute for the Early Universe, where I stayed one year. Then I moved to Sungkyunkwan University in Korea for almost three years for a post-doctoral position in the Institute of Basic Science. In 2015 I moved here to LeCosPA institute of National Taiwan University for another post-doctoral position. In my free time I like to do sport activities, particularly I like to play squash, ride bicycle, hiking, swimming, skiing, running, and I like travelling and discovering different countries.
