About Me

I obtained my first degree in physics from University of Peradeniya. After graduating with a first class honors degree, I went on to pursue a doctoral degree in condensed matter physics at the University of Connecticut, USA. My doctoral thesis work involved fabrication and characterization of superconducting thin films. I have hands-on experience with many experimental techniques such as pulsed laser deposition, neutron diffraction, nuclear magnetic resonance (NMR), synchrotron and laboratory X-ray diffraction (XRD) and synchrotron and laboratory Mossbauer spectroscopy. I am interested in fabricating and characterizing new materials and devices for various technological applications.
