Why does the immune system target one particular molecular feature over another, and how does that selection affect the evolution of cancer and viruses? Benjamin Greenbaum, Long-term Member (2008–13) in the School of Natural Sciences, highlights his work on the theory of self versus non-self discrimination.

In this excerpt, Freeman Dyson, Faculty (1952–2020) in the School of Natural Sciences, ascends the New Court clock tower at St. John’s College, Cambridge during a wartime blackout.

The unparalleled resolution of the Event Horizon Telescope (EHT) images of the black holes at the center of the M87 galaxy and at the center of our galaxy, called Sagittarius A* (Sgr A*), allows us to test assumptions, predictions, and alternatives to Einstein’s theory of gravity. 

Sophie Lund Schrøder is a Member in the School of Natural Sciences. She will spend her time at IAS applying numerical methods and analytic modeling to study high-energy astrophysical phenomena, especially evolution of stellar binaries.

In this Scholar Spotlight we feature three former scholars: Michael Hanchard (Social Science), Jo Nelson (Mathematics), and Tracy Slatyer (Natural Sciences). They explain how and why the environment at IAS nourishes independent thinkers and prompts scholars to ask questions that push the boundaries of knowledge.

Jo Dunkley is an astrophysicist who studies the origins and evolution of the universe. In this short video she explains how her love of mathematics helped her realize that math tools can help us find answers to questions about our world.
