Short Bio

Ivan Arraut is a PhD graduated from the school of Science at Osaka University. His research areas include Game Theory for applications in Business and Economy, Quantum Finance, Business Analytics and Machine Learning as well as fundamental researches in Physics and Engineering sciences. Ivan Arraut thinks that Science and Business cannot be separated because both areas need from each other in order to progress and he has learned how to combine successfully both of them. In fact, some of Ivan's best results came out by mapping some ideas from Business and economy toward fundamental sciences and viceversa, namely, by mapping ideas from fundamental sciences into ideas related to Business, economy and Financial areas. Ivan Arraut is then a multidisciplinary researcher, teaching quantitative courses at USJ in Macau. Ivan is also interested in entrepreneurship, mainly on the industries touching data analysis, financial technology, machine learning, video games, development of apps and visual animation.
Ivan Arraut has a long history in research and more than 5 years of teaching experience in different universities. He has received 10 academic prizes and/or recognitions from different institutions around the world during his career.
