The Database of Z4 Codes

Check out the new Database for Z4 Codes

My primary area of research is Algebraic Coding Theory. I received my PhD from The Ohio State University.
Here is the abstract of my PhD thesis from OSU web site.
My PhD advisor was   Prof. Dijen Ray-Chaudhuri , the letter "C" in BCH codes refers to him.
Here are some coding theorists
My areas of interest are:

  • Quasi-Cyclic (QC) and Quasi-Twisted (QT) Codes over finite fields and construction of linear codes with improved parameters
  • Codes over integers modulo 4 (quaternary codes).
  • QC/QT over Z_4 and construction of good binary (linear or nonlinear) codes.
  • Codes over more general rings
  • Algebraic Geometry Codes
  • Cryptography
  • Mathematics Education/Pedagogy
  • Theoretical Computer Science
  • History of Mathematics and Science, especially in the Islamic World
