I'm a PhD student at the University of Peradeniya and a research assistant in the Advanced Material Research Laboratory, the University of Peradeniya. I'm interested in scientific manuscript writing and other academic writing using LaTeX and MS Office. Also, I'm an expert in analyzing XDR, XRF, SEM, AFM, TEM, and UV-Visible spectroscopy. I perform scientific simulations using SCAPS-1D, Lumerical FDTD, NI LabVIEW, and Multisim. I have vast knowledge in MATLAB, OriginLab, ImageJ, and Gwyddion.
