The Department of Energy Office of Science of the United States, in connection with the armed aggression of the Russian Federation against Ukraine, provides funding for the remuneration of Ukrainian scientists to ensure a "safe and favorable environment for students, doctoral students and scientists from Ukraine to continue their research."
DOE’s Office of Science funds U.S. scientific research institutions (not directly Ukrainians) and encourages the employment of Ukrainian students, teachers, and scientists (provides them with pay and other expenses related to employment, moving to the United States, providing visa support, etc.).
Applications can be submitted to Grants.gov through an open competition (Continuation of Solicitation for the Office of Science Financial Assistance Program, currently DE-FOA0002562, e-mail: SC.DCL@science.doe.gov) at the link.
