Petr Cejka received his Master’s degree in 2000 from the Charles University in Prague and PhD in 2004 from the University of Zurich. During his PhD studies with Prof. Josef Jiricny, Petr Cejka studied the function of the mismatch repair system in human cells, as well as how mismatch repair mediates the sensitivity of DNA methylating agents used in anti-cancer therapy. Petr Cejka then received a postdoctoral fellowship from the Swiss National Science Foundation to move to the laboratory of Prof. Stephen Kowalczykowski at University of California, Davis, US. Dr. Cejka received extensive training in protein biochemistry and contributed to our understanding of homologous recombination. In 2011, Petr Cejka was awarded Assistant Professorship from the Swiss National Science Foundation and returned to the University of Zurich. Dr. Cejka then established his own independent research group. The research in Dr. Cejka’s laboratory is focused on various steps in the homologous recombination pathway. For his scientific achievements, Dr. Cejka received the Dr. Ernst Th. Jucker Award 2015 for contributions to cancer research and in 2017 the Friedrich Miescher Award from the LS2 section of Molecular and Cellular Biosciences. In 2016, Dr. Cejka received an ERC consolidator grant and moved to the Institute for Research in Biomedicine.
