His research areas include General and fundamental Physics, Engineering Science, Game Theory, Quantum Finance and Machine Learning. Ivan Arraut likes to combine research in different areas. In fact, some of Ivan's best results came out by mapping some ideas from practical areas toward fundamental sciences and viceversa, namely, by mapping ideas from fundamental sciences into ideas related to practical areas. Ivan Arraut is then a multidisciplinary researcher, teaching Physics and Mathematics at USJ in Macau. His main research characteristic is originality and simplicity, trying to find the simplest explanation for unexplained phenomena. With this style, he has received 12 academic prizes and/or recognitions from different institutions around the world during his career, including grants, scholarships, commendable thesis awards, fellowships, recognitions coming from journals, among others. Ivan Arraut has a long history with 18 years of research experience and more than 7 years of teaching experience in different universities.
