Michaela Kozlová is the head of a Ti:Sapphire laser laboratory at PALS Research Center, and is intensively involved in the program on laser-driven X-ray sources at the ELI Beamlines project. Holding a Ph.D. (2010) from the Czech Technical University in Prague, she has previously worked as a research fellow at laboratories in France, the United Kingdom, Germany, and South Korea. Her work chiefly focuses on laser-driven secondary sources in the X-ray region, including plasma-based X-ray lasers, electron acceleration by lasers, betatron or Compton X-ray sources, and their metrology and applications. Jaroslav Nejdl is currently the head of a research program on laser-driven X-ray sources at the ELI Beamlines facility. After receiving his B.Sc. (2006), M.Sc. (2009) and Ph.D. (2012) from the Czech Technical University in Prague, he spent one year at the LOA, ENSTA ParisTech, France, and a subsequent year at CSU, USA, where he worked as a research fellow. While his earlier work focused on plasma-based X-ray lasers and their applications, he is currently pursuing research into various types of laser-driven short-wavelength sources, both coherent and incoherent.
