Roswitha Rissner

Roswitha Rissner is a Senior Scientist and Privatdozent at the Department of Mathematics, University of Klagenfurt. Her academic roles include membership in the university's Senate and teaching responsibilities. She holds a PhD in Technical Mathematics from Graz University of Technology (2015) and completed her Habilitation in Mathematics in March 2024. Her research focuses on algebra, computer algebra, number theory, and combinatorics. She has held postdoctoral positions and a guest professorship in Graz.

Her educational background includes a Diplom-Ingenieur (Dipl.-Ing.) and PhD from Graz University of Technology. Key research areas include integer-valued polynomials, non-unique factorizations, monomial ideals, and applications of algebraic structures in discrete mathematics and graph theory.

Roswitha's work explores themes such as irreducible polynomials, associated prime ideals of monomial ideals, and combinatorial implications in ring theory. Her publications span topics like binomial polynomials, Ramsey numbers in graph theory, and matrix rings over finite fields.

Her research also intersects computational algebra, including J-ideal computations and null ideals of matrices. She maintains a lab or research team focused on algebraic structures and their applications, though specific lab details are not explicitly mentioned.
