Hello, World!
I am a PhD student in the Symbolic Computation Group [web] in David R. Cheriton School of Computer Science [web], Faculty of Mathematics [web] at the University of Waterloo [web]. My supervisor is Mark Giesbrecht [web].
I finished my master's degree [web] at the Department of Computing and Software [web] at McMaster University [web], Hamilton, Canada. My supervisors were Spencer Smith [web] and Jacques Carette [web]. I earned my bachelor's degree [web] from AlAzhar University, Cairo, Egypt.
Research
I work on algorithms to compute Smith normal form [wiki]
of (mostly sparse) matrices over local rings [wiki] such as the integers modulo
prime power and polynomials modulo power of an irreducible polynomial.
A theme of my work is trying to link the invariant factors and the
determinantal divisors to eigenvalues over padic [wiki] field extensions.
I am also interested in proving some properties about matrices
under the application of the remainder operator [wiki].
