      Bio:
      Domagoj Kovačević was born on January 14, 1968 in Požega, Croatia. He graduated from the High School in Zagreb. In 1986, he won bronze medal at the International Mathematical Olympiad in Poland. After the military service, he enrolled at the Department of Mathematics at the University of Zagreb. In 1993, he graduated and was enrolled as a PhD student at the University of Utah. His major interest during the graduate study was representation theory. In 2000, he came back and started to teach mathematics in XV. High School. In 2006, he defended his PhD thesis at the University of Utah. The thesis advisor was professor Gordan Savin. After that, Domagoj Kovačević became a Senior Instructor at the Faculty of Electrical Engineering and Computing at the University of Zagreb and started research collaboration with professor Stjepan Meljanac from Ruđer Bošković Intitute, where five papers were produced. In 2012, he became an Assistant Professor and started doing representation theory again. At the Faculty of Electrical Engineering and Computing he taught several undergraduate courses.

            Vita:

            Boris Širola earned a B.Sc. degree in mathematics at the Department of Mathematics, University of Zagreb, in 1988.  He also earned a M.Sc. degree in 1992. and Ph.D. in 1996., at the same institution.

            He held a position of a teaching assistant at the Department of Mathematics, University of Zagreb, since 1988. He received a permanent position of Assistant Professor in 2000., and was promoted to the rank of Associate Professor in 2005., and to the rank of Professor in 2012. An academic year 1998./99. he spent as a postdoc at the Massachusetts Institute of Technology, Cambridge, MA, USA. He has also been, as a visiting scholar, at the following institutions: Tata Institute of Fundamental Research, Mumbai (2002.); Mathematische Institut, Heinrich Heine Universitet, Dusseldorf (2005.); University of Utah, Salt Lake City (2010. i 2014.) His fields of interest are (noncommutative) algebra, group theory, number theory and mostly Lie theory; in particular, structure theory and representation theory of Lie algebras, some problems related to investigations of geometry of nilpotent orbits and flag varieties for reductive groups, and relationship with representation theory of algebraic groups.  As an only author he published 21 scientific papers in recognized mathematical journals; some of them in leading journals specialized for algebra.

            At the undergraduate study he held several courses (e.g., Algebraic structures, Theory of analytic functions). At the graduate study he created and held 4 two-semester courses (Lie algebras and representation theory, Commutative algebra, Riemann Zeta function and Introduction to the theory of analytic functions of several complex variables). He is a cofounder and coleader of the Seminar for Algebra at the University of Zagreb.
