MathAcrossCampus is a quarterly colloquium series at the University of Washington to showcase applications of mathematics, with a special emphasis on the growing role of discrete methods in math applications. The goal of this seminar is to expose theoreticians to applied work, to create a community of mathematicians and users of mathematics at UW, and to serve as a guide to students and researchers looking for projects and jobs in math-related areas by offering exposure to ongoing math applications in the Seattle area.

River networks, which branch like tree limbs across the landscape, are one of Earth’s most widespread and recognizable surface features. They have also been discovered on two other Solar System bodies, Mars and Saturn’s moon Titan. What do these striking landscape patterns tell us about the histories of alien worlds? I will show how mathematical and computational descriptions of slow-acting geological processes, combined with measurements of today’s landscapes, have provided a new perspective on the origin and evolution of river networks. I will then direct your gaze to Titan, where an exotic cocktail of materials and conditions has formed a deceptively Earth-like landscape, and show what our Earthly knowledge can teach us about this mysterious world.
MathAcrossCampus is also made possible by the efforts of UW Mathematics graduate students Clayton Barnes, Gerandy Brito Montes de Oca, Christopher Fowler, Matthew Junge, Hon Leung Lee, Avi Levy, Harishchandra Ramadas, and Jacob Richey.
