**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 Z_4 and construction of good binary (linear or nonlinear) codes.
- Codes over more general rings
- Algebraic or combinatorial constructions of codes with good parameters
- Cryptography
- History of Mathematics and Science, especially in the Islamic World
- Relationship between religion and science
- Mathematics Education/Pedagogy
- Theoretical Computer Science
