In 1981, I graduated from the Faculty of Mathematics of the University of Tartu. In 1986, I defended my dissertation at the Belarusian State University (Minsk) and received the degree of Candidate of Physical and Mathematical Sciences (equivalent to a PhD). The dissertation was devoted to the study of the geometric structure of BRST supersymmetries within the framework of the theory of connections on fiber bundles. In 1993, I was a visiting researcher at the Faculty of Mathematics of Humboldt University in Berlin within the framework of the project "Differential Geometry and Quantum Theory". In 1994, I completed a professional development program for university lecturers at the University Paris VI. In 1997, I worked as a senior researcher at the Faculty of Physics of the same university, i.e., the University Paris VI. I was a member of the organizing committee of a series of international conferences entitled “Algebra, Geometry, and Mathematical Physics” (Tartu, Gothenburg, Będlewo, Mulhouse, Västerås). Since 2011, I have been a Professor of Geometry and Topology at the Institute of Mathematics and Statistics of the University of Tartu. I am a member of the editorial boards of several international mathematical journals. At present, my research is mainly focused on ternary algebraic structures and generalizations of Lie and Poisson algebras.
