# Topology, Geometry, and Data Analysis at OSU

### Description

The TGDA group is an interdepartmental group at OSU, with faculty from with CSE, Mathematics, and Statistics whose interests span the following topics:
- clustering algorithms and Reeb graph / dendrogram reconstruction
- computational topology
- surface/manifold reconstruction and mesh generation
- computing optimal homology generators
- metric measure spaces and shape matching
- low-distortion metric embeddings
- Morse theory
- random graphs and percolation theory
- random topology
- topological graph theory
- geometric approximation algorithms
- persistent homology and cohomology, and applications
- spectral and geometric methods in machine learning and data analysis
- geometric and topological methods in data analysis
