I graduated at the University of Colombo completing Physics as a Special subject and also completed degree of Mater of Philosophy in colorimetry instrumentation at the same university. To complete My PhD in the area of Mass spectrometry Instrumentation I did research at the University of Uppsala , Sweden and University of Manitoba , Canada  . I assume that , the complicated phenomena in the nature can be understood through the   models presented in Physics . I am curious to know about the mysterious phenomena in the universe . But  I also believe that those understanding is not the reality.  .
