We are a team of grants specialists, team leaders, and branch chiefs who work together to help financially support cancer research activities throughout the United States and around the world.

Our leadership team is spread across four branches to ensure we effectively plan and direct all NCI business-related activities associated with the negation, award, and ongoing management of NCI grants and cooperative agreements.
