Here are the accomplishments obtained as a mathematician. I have studied cryptographical algorithms,
number theory for cryptography and the properties of cyclotomic polynomials.
The left gif image illustrates
the computation of R-ate pairing on elliptic curve, which
was published in 2009 by me and my colleagues, known as the most efficient pairing.
Pairing on elliptic curves has been enormously used
in cryptographic applications.
