Associate Professor, Faculty of Science
I gained PhD from Tohoku University, Japan, in 2000 and I extended my researches in several institutions including Universiti Sains Malaysia (Malaysia), Max-Born Institut fur Kurzzeitspektroskopie in Forschungsverbund in Berlin (Germany), Osaka University (Japan), Ecole Normale Superieure de Chimie Paris (France), National Chiao Tung University (Taiwan), and King Abdullah University of Science and Technology (Saudi Arabia). Now I am working in Department of Chemistry, Faculty of Science, Universiti Brunei Darussalam. So far, I published almost 200 scientific papers. I have been awarded by Japanese Ministry of Education, Science and Culture, Researcher Scholarship of Universiti Sains Malaysia, Wolfgang von Leibniz Foschungstippendium/Deutscher Akademischer Austausch Dienst (DAAD), Japan Society for the Promotion of Sciences (JSPS), Centre National de la Recherce Scientifique (CNRS) & Lâ€™Agence Nationale de la Recherche (ANR), and National Science Council (NSC) of Taiwan.
I am familiar with many scientific software, particularly those for data analyses, mathematical formulations, and simulations.
I have capability and competence to carry out researches and publications in
light-matter interactions, photophysics, photochemistry, photobiology, analytical chemistry, molecular dynamics, and nanoparticles and nanoscience.
