Title:        Cluster algebras and scattering amplitudes

Abstract: 

In recent years fruitful connections between math and physics have emerged from the study of scattering amplitudes. I will review and put into context some key concepts from this exe of ideas, involving cluster algebras, positive geometries, and the amplituhedron.  I will highlight further physics-motivated conjectures that may provide fruitful avenues for continued exchange in the years to come.
