Business Development Summary: Across the biopharma industry, business development (BD) teams serve as a unique, cross-functional window into the external landscape. Companies like Ionis leverage external partnerships to bring more drugs to patients than they otherwise might be able to on their own.

The first area of focus for this internship will be to generate BD ideas for Ionis by (1) mapping current and future core capabilities across our portfolio; (2) identifying potential disease areas and end markets that we could enter or better serve; and (3) providing recommendations to develop internal assets/technologies or acquire rights to external assets/technologies.
