Mathematics graduate student Nancy Scherich's modern dance video, "Math Dance 2," won first place in this year's Art of Science competition. Art of Science encourages members of the UCSB community to show the artistic side of their field of study, as a way of engaging the public in what can otherwise be esoteric topics. Scherich's video illustrates three different but interrelated Mathematics disciplines -- algebra, geometry, and topology. You can see the winning video, and learn about the runners-up, in The Current.

Xin Zhou, an assistant professor in the UCSB Mathematics department, has received a fellowship from the Alfred P. Sloan Foundation. This fellowship is awarded annually to researchers nominated by their peers for promising early-career achievements.

Zhou, whose research interests include differential geometry and general relativity, investigates the geometric properties of surfaces. His current research focuses on mathematical models for soap bubbles, which involve interesting differential geometry that also applies to the boundaries of black holes.

**Title:**Nonlinear detection of connections

**Time:**3:30 pm, February 21

**Location:**South Hall 6635

**Abstract:**I will discuss the geometric inverse problem of recovering a connection from the parallel transport along geodesics of a compact Riemannian manifold with strictly convex boundary or along light rays in Minkowski space. This problem is motivated by other geometric inverse problems and is tackled with a range of techniques including energy estimates, regularity results for the transport equation associated with the geodesic flow and microlocal analysis.

All female middle school students and math teachers are invited to a free day of fun STEM activities at UCSB! The UCSB AWM (Association for Women in Math) Student Chapter is hosting POWERS Day (which stands for Problem sOlving for Women to Encourage Research in STEM). The activities will include fun seminars in physics, math, and statistics, lunch at the lagoon, and more! See the event website for more information, including a schedule and how to apply.
