COVID-19 Advisory Team to the President of the Polish Academy of Sciences

Since June 30, 2020 I am a member of the interdisciplinary COVID-19 Advisory Team affiliated with the President of the Polish Academy of Sciences. Our task is to monitor the course of the COVID-19 epidemic in Poland, analyze and predict its possible scenarios and put forward recommendations. We also develop contacts with similar teams in other countries to exchange experience with them.
