• We are organizing the IFIPT TC-7 Workshop “Optimization in the Länd” (OptiLänd). The workshop is planned as a joint meeting between the IFIP-TC7 working groups on Inverse problems (WG 7.4) Nonlinear optimisation (WG 7.8), and organised by the mathematical optimisation and scientific computing labs in Mannheim and Heidelberg. Thematically, the workshop is focussed on the interface between inverse problem and mathematical optimisation.  Great Speakers at a great location!
• The paper “Asymptotic Behavior of Penalty Dynamics for Constrained Variational Inequalities”, joint with Siqi Qu and Juan Peypouquet is published in Applied Mathematics & Optimization!
• New preprints out there: 

Dvurechensky, Pavel, Meggie Marschner, Shimrit Shtern, and Mathias Staudigl. “Extragradient methods with complexity guarantees for hierarchical variational inequalities.” arXiv preprint arXiv:2512.20791 (2025).
