Dr. Anuradha Mahasinghe received the University of Colombo doctoral grant in 2011 to engage in a collaborative research program with University of Western Australia, Perth. In Perth he was attached to the research group on quantum computation and quantum information, led by Prof. Jingbo Wang, a theoretical physicist. The doctoral research was mainly on mathematical aspects of quantum walks, and partly on providing efficient solutions to linear algebraic problems through quantum circuits. After finishing the PhD in 2016, he received a postdoctoral fellowship in Department of Computer Science, University of Auckland. In Auckland, he worked with Prof. Michael J. Dinneen, a well-known graph theorist and computer scientist. The postdoctoral research work was mainly on providing efficient solutions to NP-complete graph problems through the world’s first commercially available quantum computer developed by the Canadian company D-Wave. He is currently working on optimization metaheuristics and unconventional computing methods. Further, he is an enthusiast in recreational mathematics and has authored and translated several articles, books on this topic.
