H2O: Higher-Order Pattern-Discovery in High-Dimensional Data, Aarhus University, Denmark, March 30-31 2026

Christian Pascal Hirsch writes:
It is our pleasure to announce the workshop “H2O: Higher-Order pattern-discovery in High-dimensional data ” at Aarhus University, March 30 & 31, 2026. This is a two-day event designed to forge new connections across three distinct fields of modern statistical research: topological data analysis (TDA), time-series analysis (TSA), and high-dimensional statistics (HDS). At the intersection of these fields lies the critical challenge of identifying patterns in complex data structures, particularly in network data. The workshop features presentations by leading experts in the respective disciplines. 

Our primary audience includes both senior and junior researchers working in mathematical statistics and data science.

The invited lecturers are:

We can provide a very small number of accommodation in double rooms for PhD students/postdocs who have no other funding possibilities (separated by gender). Similarly, we can provide reimbursement for train/flight tickets to a very small number of PhD students/postdocs (at most DKK 1500 per person).

Deadline for registration with submitted talk/request for reimbursement: December 12, 2025

Dear all,
I am pleased to announce that I am recruiting a postdoctoral researcher in applied algebraic topology with applications to broad biological systems at the MPI-CBG in Dresden. This position offers the opportunity to conduct independent research while collaborating closely with our mathematics, network analysis, and biology groups across the institute. 

In addition to these collaborations, particularly with the applied mathematics groups of Heather Harrington, Türkü Özlüm Çelik, Aida Maraj, and Carl Modes, the position also provides the chance to engage in a broader collaboration network, connecting with the Max Planck Institute for Mathematics in the Sciences in Leipzig and the Centre for Topological Data Analysis of the University of Oxford, as well as with the geometry and topology groups at TU Dresden (e.g., Ulrich Krähmer’s group, Andreas Thom’s group). 

The application deadline for this position is 16 November 2025, with a flexible start date in 2026. All terms, funding information, and additional details are available in the advertisement attached or on the application site:

Conference on TDA: Recent Developments and Applications, University of Missouri – Columbia, November 22-24, 2025

Organizers Calin Chindris and Zhengchao Wan of the University of Missouri-Columbia are organizing the “Conference on Topological Data Analysis:
Recent Developments and Applications” this November 22-24. 

This three-day conference brings together leading researchers from academia and industry, together with graduate students and post-doctoral scholars, to discuss the latest theoretical breakthroughs and applications of Topological Data Analysis (TDA).

A central goal is to train the next generation of TDA researchers by providing a venue to present work, receive feedback, and build collaborations. TDA is evolving rapidly across theory, algorithms, and real-world applications, and our program balances cutting-edge theory with demonstrations of impact in fields ranging from machine learning to biology and network science.
