About


The TDA group at CUNY is centered around Mikael Vejdemo-Johansson, Assistant Professor of Data Science at CUNY College of Staten Island and Doctoral Faculty / Deputy Executive Officer in Computer Science / Data Science at the CUNY Graduate Center.

We run a weekly seminar, jointly with Azita Mayeli (CUNY Graduate Center - Mathematics).

Our interests are far ranging, but some core themes include:

  • Persistent Homology
  • Persistent Cohomology
  • and Circular Coordinates
  • on Time Series
  • The Mapper algorithm
  • Theory
  • Novel Applications
  • TDA Software
  • Maintains the only Java- and Matlab-platform TDA package

But also...

  • Statistical approaches to Semantics of Color Naming Systems
  • Enumerative Combinatorics
  • of tieknots
  • and formal languages
  • Mathematical Art
  • 3D-printing
  • Laser-cutting
  • Reifying topology and geometry
  • Spatial Statistics
  • Bayesian Methods
