After a severe crack in exchange rate between EUR and CZK, national call on the research budget of Czech Republic had been canceled after organizing and concluding on the competition, expertise of institutions, and selections of research teams. As a result, a number of position had been canceled, including mine. However, my post-doc in Germany was already finishing.
The proof of the scandal is available in Czech language, here.
Separately, I had met with Dr. Heiko Appel in Berlin, whom advised me to write a Marie Curie individual fellowship to apply in his laboratory.
