Research.

Research interests:

  • Algebraic geometry: In particular, low-codimenson projective varieties, grassmannians, applications of formal geometry to projective geometry and syzygies.
  • Computer algebra and geometry: In particular, topology algorithms for algebraic curves and surfaces, fast matrix multiplication and GPS/LPS closed form solutions
