• Math210: Discrete Mathematics I

Research Interests:

• • Finite fields and applications.
  • Polynomials over finite fields, particularly their roles in projective geometry, information security and combinatorics.
  • Construction of cryptographically useful functions such as APN functions and PPs with low differential uniformity.
  • Construction and classification of Cartesian groups, quasifields and semifields.
  • Automorphism groups of combinatorial and algebraic objects, and the interrelated problems of isotopy of algebraic objects and isomorphism of projective planes.
  • Projective planes, the Prime Power Conjecture and the Prime=Desargues Conjecture.
