University Education:
I graduated with a B.Sc.(Hons) Degree in Mathematics from the University of Kelaniya , Sri Lanka in 1993 and then obtained Diploma in Mathematical Statistics from the Cambridge University UK in 1998. This is the Cambridge University Statslab 1997 Photo. You can read the summary my applied project here among others'.

And I was a research student in the Mase Laboratory in the Department of Mathematical and Computing Sciences of the Tokyo Institute of Technology Japan for the year 2001/02 and then I obtained M.Sc.Degree and D.Sc. Degree in Mathematical and Computing Sciences in 2004 and 2007 respectively from the same place. Here is my Doctoral Degree Thesis which is supervised by Prof. Shigeru Mase .

Employments:
I was a Temporary Tutor in Mathematics at the University of Kelaniya , Sri Lanka for the Academic Year 1993/94 and then I worked as an Actuarial Assistant in Union Assurance Ltd Colombo Sri Lanka for two years (1994-1996). In 1996 I joined Wayamba University , Sri Lanka as a Lecturer in Mathematics.

Currently I am a Postdoctoral Research Fellow in the Akiyama Laboratory in the Department of Computer Science of the Tokyo Institute of Technology Japan.
