Short bio

Taught math and math related courses at University Halle-Wittenberg (Germany), IMPA, Rio de Janeiro (Brazil), Princeton University and Yeshiva University New York (USA).

Co-developed new area “Set Optimization” with surprising applications in mathematical finance, economics, statistics, game theory and multi-criteria decision making; invented set optimization approach to risk measures for multivariate positions.
