Welcome to my website. I am a mathematician, currently employed as postdoc at the Department of Mathematics at Alpen-Adria-Universität Klagenfurt.

I am tech-savvy and particularly fond of developing and using algorithmic methods in order to formulate and prove mathematical conjectures. My mathematical research interests are

  • computer algebra, algebra, number theory, modules and algebras over commutative rings, linear algebra over commutative rings
  • integer-valued polynomials, (multivariate) polynomials and polynomials functions over fields as well as possibly non-commutative rings
  • non-unique factorizations
  • primary decompositions of ideals/modules and associated primes
  • combinatorial commutative algebra, simplicial complices, Stanley-Reisner rings
  • integer optimization
  • graph theory, centrality notions in graphs
  • topological properties of rings and modules
  • algebraic system theory
  • developing and implementing algorithms for the topics above
