Yuri Latushkin, a Professor of Mathematics at the University of Missouri (link here) is visiting the department this week (24-28 June).  His hosts for the visit are Gianne Derks and Claudia Wulff, and the visit is funded by the Research in Pairs programme of the London Mathematical Society. Yuri has wide ranging research interests in dynamical systems, nonlinear PDEs, and fluids.  He gave a talk to the department on Wednesday on the Maslov index (announcement here). The photo left shows Gianne and Yuri in discussion after the seminar, and the photo below shows Yuri during the seminar.
