Asiri Nanayakkara


Professor A Nanayakkara is a Senior Research Professor at the NIFS since 2009. He graduated with honors from the University of Colombo, Sri Lanka with a B.Sc special degree in Mathematics. He received his PhD and MS degrees in Physics from Iowa State University (USA) and Ohio University (USA) respectively. For his PhD, he developed the Quantum Action Variable Theory of Scattering. He also developed theoretical and numerical methods to analyze the zeros of solutions of Sturm-Liouville type differential equations in the complex plane and studied Relativistic Two-Body wave equations. Prof Nanayakkara has gained postdoctoral research experience in Theoretical and Computational Physics and High performance computing from the University of Bristol UK, Ames Laboratory USA and Supercomputer Computations Research Institute USA. He has worked as a computational scientist at CRAY Research Inc, USA and was involved in Massively Parallel Computing on supercomputer systems. Prof Nanayakkara has over 100 research publications in the areas of Quantum Mechanics, High performance computing, Molecular Physics, and Artificial Intelligence. He has served as a council member of the National Research Council, Sri Lanka from 2005 to 2011 and served as a member of Research Panel on Basic Sciences at NSF for several years. Prof Nanayakkara has 22 years of research and development experience from research laboratories and computer industry in the USA and UK and 23 years of research and teaching experience in Sri Lankan Universities and the National Institute of Fundamental Studies. He also developed a part of the GAUSSIAN Computational Chemistry software package which is the most widely used Ab initio Molecular Structure Code in the world.
