Josh Thompson’s research

I am interested in geometry and topology and their applications to data analysis, computer vision, and machine learning. I also enjoy mentoring undergraduate research projects in these areas. Below are links to some of my work, software, and resources for students interested in pursuing research in these areas.

geometry, topology and their applications

• visualizing topology
• visualizing geometry
  • hyperbolic geometry
  • frenet frames on helix w/code here
  • parallel transport on a torus w/code here
• geometric and topological data analysis
• visualizing data
• math education
  • what if ax=b meant ax=me?
• algorithms on manifolds
• anomaly detection algorithms

undergraduate research

• fun with fourier

master’s thesis i’ve advised

• visualizing geometric structures on topological surfaces
• quandles that are knot quandles
