Research

My research topic is Geometric Algebra.

One focus is Geometric Algebra Computing. We define it as

  • the interactive and visual development and
  • the efficient implementation

of geometrically intuitive algorithms based on
Geometric Algebra.


Please find a brief introduction to Geometric Algebra Computing here

For more detailed information on Geometric Algebra please find the tutorial script „Aspects of Geometric Algebra in Euclidean, Projective and Conformal Space“ and download my visual example scripts based on the CLUCalc software 4.0.1.

Please find some information about Gaalop, our tool for the efficient implementation of geometric algebra algorithms, on the Gaalop homepage.
