is a 3+1-year NCN (National Science Centre, Poland) founded grant for a project (No. 2018/31/D/ST2/00813) entitled: “The impact of non-equilibrium and thermal effects on the evolution of Dark Matter in the Early Universe plasma”

The project started in July 2019 and was carried out by me (PI) and postdoc Maxim Laletin, together with number of external collaborators.

Within this project the public code DRAKE has been developed.
