WELCOME TO NGAMTA'S WEBSITE
Who am I?
My name is Ngamta Thamwattana, or some people call me ``Natalie". I am
from a little province in the South of Thaildnd,
I finised high school in my home town and then continued my study at
Mahidol University, Bangkok. I was a science student at 1st year and in
the 2nd year I chose major Mathematics. The reason was that we didn't have
to play with the chemical stuffs and we didn't have to
kill rat or any insects. In my 2nd year, I received the scholarship
from IPST (Institute of teaching Science and Technology), Thailand and
this scholarship supported me until I completed my PhD in 2005.
Continuum mechanics of flowing granular material.
The analytical solutions for Rat-holes, Sand-piles.
Mathematical modelling in nanotechnology.
Doctor of Philosophy degree in Applied Mathematics from the
University of Wollongong, Australia. Thesis title,
``Some Analytical Solutions for Problems Involving Highly Frictional
Supervisor: Professor James M. Hill.
Bachelor of Science (Maths) Hons. degree from the Mahidol University(
http://www.mahidol.ac.th), Thailand 1997-2000.
