WEIVI’s CEO and founder, Alia Dannenberg, has a PhD in theoretical physics, and in the academic world, she has done pioneering work in developing computer-assisted physics via scientific computing and mathematical modelling. Although her subject field was quantum physics, she has solved numerous previously unsolvable problems in various fields of science, e.g., in economics. Optimisation method for train traffic in disruptions is her latest innovation, and WEIVI develops it into a software tool for train traffic management.
