Department of Mathematics - Seminar on PDE - Dynamics of concentrated vorticities in 2D and 3D Euler flows
A classical problem that traces back to Helmholtz and Kirchhoff is the understanding of the dynamics of solutions to the Euler equations of an inviscid incompressible fluid when the vorticity of the solution is initially concentrated near isolated points in 2d or vortex

Department of Mathematics - PhD Student Seminar - Split Knockoffs: towards Controlling Directional False Discovery Rate under Transformations
Multiple comparisons in hypothesis test are often subject to structural constraints in applications. In structural Magnetic Resonance Imaging for Alzheimer's Disease, one studies not only the atrophy brain regions, but also comparisons of anatomically adjacent regions.
