View Curriculum Vitae

Associate Professor Andrew Bettiol obtained his PhD at the University of Melbourne, Australia in 1999 working on ion beam-induced luminescence generated by mega-electron volt ion beams. He joined the National University of Singapore in November 1999 as an NSTB fellow working on developing a proton beam-writing lithography system. In 2007, he was appointed as an Assistant Professor in the Department of Physics and the Engineering Science programme where he taught multidisciplinary design projects and photonics/optics to engineering science students. In 2014 he was given tenure and promoted to an Associate Professor. Professor Bettiol continues to hold his position as Associate Professor of Science in the Department of Physics at NUS.
