Dr. 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.
Dr. Catoiu's research is in non-commutative algebra (representation theory, enveloping algebras, Hopf algebras, quantum groups, group algebras and PI-algebras), real analysis (generalized and quantum derivatives), number theory (zeta functions, Diophantine equations) and geometry (analytic, Euclidean, convex and quantum Euclidean geometries).
