Description: The community around geometric statistics – its theory, application, and computation – is growing both in numbers and in breadth. This ranges from increasing interaction with related research communities such as manifold statistics, topological data analysis, and geometric machine learning to fertilization of the applied sciences such as biostructure and biomedical modeling and imaging.
This dual trimester program will foster and expand interactions among the above disciplines within the mathematical sciences. The focus will be on the following six topics:
- Geometric structure of data objects and suitable spaces,
- Stochastic analysis on manifolds and singular spaces,
- Statistical behavior and geometry,
- Applied topology,
- Non-Euclidean learning,
- Computational methods for all of the topics listed above.
The dual trimester program will include a
- Introductory School: Geometric Statistics
- Workshop I: stochastic analysis on manifolds and singular spaces, statistics and computation
- Workshop II: geometry, topology, and learning on smooth and singular spaces
- Conference: Interactions of Statistics and Geometry III [ISAG III]

Global Mobility Fellowships
Our Global Mobility Fellowships offer fully-funded and fully-organized visits to the Trimester Programs of the Hausdorff Research Institute for Mathematics and participation spots for the Special Topic Schools of the Hausdorff School for Mathematics for selected researchers and PhD students from countries of the Global South. With this program we aim to reduce economic and practical barriers to participation in some of the core initiatives of HCM and to welcome researchers from around the world to our programs and events!

5 minute walk from Bonn central train station to HIM
Leave the station through the back exit into the street called Quantiusstrasse. Cross at the zebra crossing and turn left. Walk to the corner: the cross-street is the Poppelsdorfer Allee. Cross (careful of traffic from your left) and walk to the right up the Poppelsdorfer Allee, towards the Poppelsdorfer Castle in the distance. At the next intersection, continue straight on up the avenue. HIM is building No. 45 on the left side of Poppelsdorfer Allee behind the wrought iron gate.
The airport shuttle drops you in front of the central train station. Cross at the traffic light nearest you and take the escalator down to the underground passage. Go straight to the end of the passageway until you reach the street (Quantiusstrasse) and follow the directions above.
If you are coming to a Workshop or School, go straight to Poppelsdorfer Allee 45 and sign-in.
If you are coming for a (Junior) Trimester Program, come first to the HIM Administration at Poppelsdorfer Allee 82, diagonally across the street from the Institute proper.
