Title: Morphogenesis: geometry, physics and biology

Abstract: A century after the publication of D'Arcy Thompson's classic On growth and form his vision has finally begun to permeate into the fabric of modern biology. Within this framework, I will show how a combination of biological and physical experiments, mathematical models and computations allow us to begin unraveling the physical basis for morphogenesis in the context of examples such as shoots, leaves, guts and brains.

Title: Voting in Agreeable Societies

Abstract: When does a candidate have the approval of a majority? How does the geometry of the political spectrum influence the outcome? What does mathematics have to say about how people behave? When mathematical objects have a social interpretation, the associated results have social applications. We will show how some classical mathematics can be used to understand voting in "agreeable" societies. This talk also features research with undergraduates.
