I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.

The consequences are profound—how many brilliant minds are being shut out of research entirely? How much future discovery is being lost before it even begins?
