MEET OUR IGC FELLOWS

The Interfaces of Global Change IGEP provides PhD students with a unique intellectual focus and training. Each IGC Fellow gains depth in their specific scientific area of expertise (e.g. biology or engineering), while simultaneously gaining breadth in the multifaceted realm of global change and the science-policy interface.

The IGC Graduate Student Association exists to benefit the IGC community as a whole through student contributions to infrastructural, educational, and social investments and activities.
