Stefan Catoiu

​Stefan Catoiu earned his PhD in mathematics in 1997 from the University of Wisconsin-Madison, where he worked under the guidance of Professor Donald Passman. Catoiu then spent two years as a Visiting Assistant Professor at Temple University in Philadelphia, before joining the faculty at DePaul University in 1999.
 
Catoiu's research area is non-commutative algebra, with particular focus on the representation theory of Lie algebras, enveloping algebras, Hopf algebras and quantum groups. He is also interested in applying abstract algebra to other areas like analysis (quantum derivatives) and number theory (zeta functions).
